Refunction

Where the numbers λ and μ may be complex, and are called the degree and order of the relevant function, respectively. The polynomial solutions when λ is an integer (denoted n), and μ=0 are the Legendre polynomials P n; and when λ is an integer (denoted n), and μ=m is also an integer with m.

Changed in version 3.7: is raised if a character set contains constructsthat will change semantically in the future. A B, where A and B can be arbitrary REs, creates a regular expression thatwill match either A or B. An arbitrary number of REs can be separated by the' ' in this way. This can be used inside groups (see below) as well. Asthe target string is scanned, REs separated by ' ' are tried from left toright.

When one pattern completely matches, that branch is accepted. This meansthat once A matches, B will not be tested further, even if it wouldproduce a longer overall match. In other words, the ' ' operator is nevergreedy. To match a literal ' ', use , or enclose it inside acharacter class, as in. (.)Matches whatever regular expression is inside the parentheses, and indicates thestart and end of a group; the contents of a group can be retrieved after a matchhas been performed, and can be matched later in the string with the numberspecial sequence, described below.

To match the literals '(' or ')',use ( or ), or enclose them inside a character class: (, ). (?)This is an extension notation (a '?' Following a '(' is not meaningfulotherwise). The first character after the '?'

Determines what the meaningand further syntax of the construct is. Extensions usually do not create a newgroup; (?P.) is the only exception to this rule. Following are thecurrently supported extensions. (?aiLmsux)(One or more letters from the set 'a', 'i', 'L', 'm','s', 'u', 'x'.) The group matches the empty string; theletters set the corresponding flags: (ASCII-only matching),(ignore case), (locale dependent),(multi-line), (dot matches all),re.U (Unicode matching), and (verbose),for the entire regular expression.(The flags are described in.)This is useful if you wish to include the flags as part of theregular expression, instead of passing a flag argument to thefunction. Flags should be used first in theexpression string. (?.)A non-capturing version of regular parentheses.

Matches whatever regularexpression is inside the parentheses, but the substring matched by the groupcannot be retrieved after performing a match or referenced later in thepattern. (?aiLmsux-imsx.)(Zero or more letters from the set 'a', 'i', 'L', 'm','s', 'u', 'x', optionally followed by '-' followed byone or more letters from the 'i', 'm', 's', 'x'.)The letters set or remove the corresponding flags:(ASCII-only matching), (ignore case),(locale dependent), (multi-line),(dot matches all), re.U (Unicode matching),and (verbose), for the part of the expression.(The flags are described in.)The letters 'a', 'L' and 'u' are mutually exclusive when usedas inline flags, so they can’t be combined or follow '-'. Instead,when one of them appears in an inline group, it overrides the matching modein the enclosing group.

In Unicode patterns (?a.) switches toASCII-only matching, and (?u.) switches to Unicode matching(default). In byte pattern (?L.) switches to locale dependingmatching, and (?a.) switches to ASCII-only matching (default).This override is only in effect for the narrow inline group, and theoriginal matching mode is restored outside of the group. Changed in version 3.5: Added support for group references of fixed length. (?

Similar topositive lookbehind assertions, the contained pattern must only match strings ofsome fixed length. Patterns which start with negative lookbehind assertions maymatch at the beginning of the string being searched. (?(id/name)yes-pattern no-pattern)Will try to match with yes-pattern if the group with given id orname exists, and with no-pattern if it doesn’t.

No-pattern isoptional and can be omitted. For example,(<)?(w+@w+(?.w+)+)(?(1) $)="" is="" a="" poor="" email="" matching="" pattern,="" whichwill="" match="" with="" '="" as="" well="" as="" 'user@host.com',="" butnot="" with="" '.the="" special="" sequences="" consist="" of="" '="" and="" a="" character="" from="" the="" list="" below.if="" the="" ordinary="" character="" is="" not="" an="" ascii="" digit="" or="" an="" ascii="" letter,="" then="" theresulting="" re="" will="" match="" the="" second="" character.="" for="" example,="" $="" matches="" thecharacter="" '$'.="" numbermatches="" the="" contents="" of="" the="" group="" of="" the="" same="" number.="" groups="" are="" numberedstarting="" from="" 1.="" for="" example,="" (.+)="" 1="" matches="" 'the="" the'="" or="" '55="" 55',but="" not="" 'thethe'="" (note="" the="" space="" after="" the="">

This special sequencecan only be used to match one of the first 99 groups. If the first digit ofnumber is 0, or number is 3 octal digits long, it will not be interpreted asa group match, but as the character with octal value number. Inside the' and ' of a character class, all numeric escapes are treated ascharacters. AMatches only at the start of the string. BMatches the empty string, but only at the beginning or end of a word.A word is defined as a sequence of word characters. Note that formally,b is defined as the boundary between a w and a W character(or vice versa), or between w and the beginning/end of the string.This means that r'bfoob' matches 'foo', 'foo.' , '(foo)','bar foo baz' but not 'foobar' or 'foo3'.By default Unicode alphanumerics are the ones used in Unicode patterns, butthis can be changed by using the flag.

Word boundaries aredetermined by the current locale if the flag is used.Inside a character range, b represents the backspace character, forcompatibility with Python’s string literals. BMatches the empty string, but only when it is not at the beginning or endof a word. This means that r'pyB' matches 'python', 'py3','py2', but not 'py', 'py.' .B is just the opposite of b, so word characters in Unicodepatterns are Unicode alphanumerics or the underscore, although this canbe changed by using the flag. Word boundaries aredetermined by the current locale if the flag is used.

D For Unicode (str) patterns:Matches any Unicode decimal digit (that is, any character inUnicode character category Nd). This includes 0-9, andalso many other digit characters. If the flag isused only 0-9 is matched. For 8-bit (bytes) patterns:Matches any decimal digit; this is equivalent to 0-9. DMatches any character which is not a decimal digit. This isthe opposite of d.

If the flag is used thisbecomes the equivalent of ^0-9. S For Unicode (str) patterns:Matches Unicode whitespace characters (which includes tnrfv, and also many other characters, for example thenon-breaking spaces mandated by typography rules in manylanguages). If the flag is used, only tnrfv is matched. For 8-bit (bytes) patterns:Matches characters considered whitespace in the ASCII character set;this is equivalent to tnrfv. SMatches any character which is not a whitespace character. This isthe opposite of s. If the flag is used thisbecomes the equivalent of ^ tnrfv.

W For Unicode (str) patterns:Matches Unicode word characters; this includes most charactersthat can be part of a word in any language, as well as numbers andthe underscore. If the flag is used, onlya-zA-Z0-9 is matched. For 8-bit (bytes) patterns:Matches characters considered alphanumeric in the ASCII character set;this is equivalent to a-zA-Z0-9. If the flag isused, matches characters considered alphanumeric in the current localeand the underscore. WMatches any character which is not a word character. This isthe opposite of w. If the flag is used thisbecomes the equivalent of ^a-zA-Z0-9.

If the flag isused, matches characters which are neither alphanumeric in the current localenor the underscore. ZMatches only at the end of the string.Most of the standard escapes supported by Python string literals are alsoaccepted by the regular expression parser. A b f n N r t u U v x (Note that b is used to represent word boundaries, and means “backspace”only inside character classes.)'u', 'U', and 'N' escape sequences are only recognized in Unicodepatterns. In bytes patterns they are errors. Unknown escapes of ASCIIletters are reserved for future use and treated as errors.Octal escapes are included in a limited form.

If the first digit is a 0, or ifthere are three octal digits, it is considered an octal escape. Otherwise, it isa group reference. As for string literals, octal escapes are always at mostthree digits in length. Changed in version 3.7: Compiled regular expression objects with the flag nolonger depend on the locale at compile time. Only the locale atmatching time affects the result of matching.

MULTILINEWhen specified, the pattern character '^' matches at the beginning of thestring and at the beginning of each line (immediately following each newline);and the pattern character '$' matches at the end of the string and at theend of each line (immediately preceding each newline). By default, '^'matches only at the beginning of the string, and '$' only at the end of thestring and immediately before the newline (if any) at the end of the string.Corresponds to the inline flag (?m). DOTALLMake the '.' Special character match any character at all, including anewline; without this flag, '.'

Will match anything except a newline.Corresponds to the inline flag (?s). VERBOSEThis flag allows you to write regular expressions that look nicer and aremore readable by allowing you to visually separate logical sections of thepattern and add comments. Whitespace within the pattern is ignored, exceptwhen in a character class, or when preceded by an unescaped backslash,or within tokens like.?, (?: or (?P.When a line contains a # that is not in a character class and is notpreceded by an unescaped backslash, all characters from the leftmost such# through the end of the line are ignored.This means that the two following regular expression objects that match adecimal number are functionally equal. Compile ( r 'd + # the integral part. # the decimal point d. # some fractional digits', re.

Compile ( r 'd+.d.' )Corresponds to the inline flag (?x). Search ( pattern, string, flags=0 )Scan through string looking for the first location where the regular expressionpattern produces a match, and return a corresponding. Return None if no position in the string matches thepattern; note that this is different from finding a zero-length match at somepoint in the string. Match ( pattern, string, flags=0 )If zero or more characters at the beginning of string match the regularexpression pattern, return a corresponding.

Return None if the string does not match the pattern;note that this is different from a zero-length match.Note that even in mode, will only matchat the beginning of the string and not at the beginning of each line.If you want to locate a match anywhere in string, useinstead (see also ). Fullmatch ( pattern, string, flags=0 )If the whole string matches the regular expression pattern, return acorresponding.

Return None if thestring does not match the pattern; note that this is different from azero-length match. Split ( r 'W+', 'Words, words, words.' ) 'Words', 'words', 'words', ' re. Split ( r '(W+)', 'Words, words, words.'

) 'Words', ', ', 'words', ', ', 'words', '.' , ' re. Split ( r 'W+', 'Words, words, words.' , 1 ) 'Words', 'words, words.'

Split ( 'a-f+', '0a3B9', flags = re. IGNORECASE ) '0', '3', '9'If there are capturing groups in the separator and it matches at the start ofthe string, the result will start with an empty string. The same holds forthe end of the string. Changed in version 3.7: Non-empty matches can now start just after a previous empty match. Sub ( pattern, repl, string, count=0, flags=0 )Return the string obtained by replacing the leftmost non-overlapping occurrencesof pattern in string by the replacement repl.

If the pattern isn’t found,string is returned unchanged. Repl can be a string or a function; if it isa string, any backslash escapes in it are processed. That is, n isconverted to a single newline character, r is converted to a carriage return, andso forth. Unknown escapes of ASCII letters are reserved for future use andtreated as errors.

Other unknown escapes such as & are left alone.Backreferences, suchas 6, are replaced with the substring matched by group 6 in the pattern.For example. print ( re. Escape ( ')) legalchars = string.

Asciilowercase + string. Digits + '!#$%&'.+.^` :' print ( '%s +'% re. Escape ( legalchars )) abcdefghijklmnopqrstuvwxyz!#$%&'.+.^` :+ operators = '+', '-', '.' , '/', '.' print ( ' '. Join ( map ( re.

Escape, sorted ( operators, reverse = True )))) / - +.This function must not be used for the replacement string inand, only backslashes should be escaped. Changed in version 3.7: Only characters that can have special meaning in a regular expressionare escaped. As a result, '!' , ', '%', ', ',','/', ':', ';', ', '@', and'`' are no longer escaped.

Purge ( )Clear the regular expression cache. Exception re. Error ( msg, pattern=None, pos=None )Exception raised when a string passed to one of the functions here is not avalid regular expression (for example, it might contain unmatched parentheses)or when some other error occurs during compilation or matching. It is never anerror if a string contains no match for a pattern. The error instance hasthe following additional attributes: msgThe unformatted error message. PatternThe regular expression pattern.

PosThe index in pattern where compilation failed (may be None). LinenoThe line corresponding to pos (may be None). ColnoThe column corresponding to pos (may be None).

Regular Expression ObjectsCompiled regular expression objects support the following methods andattributes: Pattern. Search ( string , pos , endpos )Scan through string looking for the first location where this regularexpression produces a match, and return a corresponding. Return None if no position in the string matches thepattern; note that this is different from finding a zero-length match at somepoint in the string.The optional second parameter pos gives an index in the string where thesearch is to start; it defaults to 0. This is not completely equivalent toslicing the string; the '^' pattern character matches at the real beginningof the string and at positions just after a newline, but not necessarily at theindex where the search is to start.The optional parameter endpos limits how far the string will be searched; itwill be as if the string is endpos characters long, so only the charactersfrom pos to endpos - 1 will be searched for a match.

If endpos is lessthan pos, no match will be found; otherwise, if rx is a compiled regularexpression object, rx.search(string, 0, 50) is equivalent torx.search(string:50, 0). pattern = re. Compile ( 'd' ) pattern. Search ( 'dog' ) # Match at index 0 pattern. Search ( 'dog', 1 ) # No match; search doesn't include the 'd' Pattern. Match ( string , pos , endpos )If zero or more characters at the beginning of string match this regularexpression, return a corresponding.Return None if the string does not match the pattern; note that this isdifferent from a zero-length match.The optional pos and endpos parameters have the same meaning as for themethod.

pattern = re. Compile ( 'o' ) pattern. Match ( 'dog' ) # No match as 'o' is not at the start of 'dog'.

Match ( 'dog', 1 ) # Match as 'o' is the 2nd character of 'dog'. If you want to locate a match anywhere in string, useinstead (see also ).

Fullmatch ( string , pos , endpos )If the whole string matches this regular expression, return a corresponding. Return None if the string does notmatch the pattern; note that this is different from a zero-length match.The optional pos and endpos parameters have the same meaning as for themethod. New in version 3.4. Split ( string, maxsplit=0 )Identical to the function, using the compiled pattern.

Findall ( string , pos , endpos )Similar to the function, using the compiled pattern, butalso accepts optional pos and endpos parameters that limit the searchregion like for. Finditer ( string , pos , endpos )Similar to the function, using the compiled pattern, butalso accepts optional pos and endpos parameters that limit the searchregion like for. Sub ( repl, string, count=0 )Identical to the function, using the compiled pattern. Subn ( repl, string, count=0 )Identical to the function, using the compiled pattern. FlagsThe regex matching flags.

This is a combination of the flags given to, any (?) inline flags in the pattern, and implicitflags such as UNICODE if the pattern is a Unicode string. GroupsThe number of capturing groups in the pattern. GroupindexA dictionary mapping any symbolic group names defined by (?P) to groupnumbers. The dictionary is empty if no symbolic groups were used in thepattern. PatternThe pattern string from which the pattern object was compiled. Changed in version 3.5: Unmatched groups are replaced with an empty string. Group ( group1.

)Returns one or more subgroups of the match. If there is a single argument, theresult is a single string; if there are multiple arguments, the result is atuple with one item per argument. Without arguments, group1 defaults to zero(the whole match is returned). If a groupN argument is zero, the correspondingreturn value is the entire matching string; if it is in the inclusive range1.99, it is the string matching the corresponding parenthesized group. If agroup number is negative or larger than the number of groups defined in thepattern, an exception is raised. If a group is contained in apart of the pattern that did not match, the corresponding result is None.If a group is contained in a part of the pattern that matched multiple times,the last match is returned.

Match ( r '(w+) (w+)', 'Isaac Newton, physicist' ) m. Group ( 0 ) # The entire match 'Isaac Newton' m.

Since 1899, Shank’s has been a valuable ingredient and packaging partner for the food and beverage industry. We have the technical aptitude for creating precise formulations and the business commitment to ongoing R&D innovation. Lamb shanks are slowly simmered with fresh rosemary, garlic, tomatoes, and red wine. Great served with polenta, or my family's favorite-roasted garlic mashed potatoes-as you need something to soak up the wonderful sauce. Shank definition is - the part of the leg between the knee and the ankle in humans or the corresponding part in various other vertebrates. How to use shank in a sentence. Slang A knife or other sharp, pointed implement, especially one that has been fashioned from something else; a shiv. Shanked, shanking, shanks Sports 1. Shanks is a relatively tall man (just under two meters), well-built, tan-complexioned, and in the prime of his mid-adulthood. Among the Yonko past and present, he notably stands out as the smallest, most normal-sized by far, the others being various degrees of inhumanly proportioned.

Group ( 1 ) # The first parenthesized subgroup. 'Isaac' m. Group ( 2 ) # The second parenthesized subgroup. 'Newton' m. Group ( 1, 2 ) # Multiple arguments give us a tuple.

Beyond the beyond wiki. ('Isaac', 'Newton')If the regular expression uses the (?P.) syntax, the groupNarguments may also be strings identifying groups by their group name. If astring argument is not used as a group name in the pattern, anexception is raised.A moderately complicated example.

Refunktion is a cool first-person stealth action game with a focus on speed runs and challenging gameplay that’s aimed squarely at the hardcore player.The clean visual aesthetic of Refunction is reminiscent of Portal, but it shares more in common with Metal Gear Solid or Mirrors Edge. Levels offer multiple routes and lots of roaming robotic enemies. Stealth is key, you have no combat moves and if the enemy spots you and shoots you once, you die and have to start the level again.As well as being as stealthy as possible, you’ll also have to be as fast as possible – mapping out routes and shaving vital seconds off to get a fastest time (Though a lot of the time you’ll just be happy to get to the end of the level in one piece!).
