ure – regular expressions

This module implements regular expression operations. Regular expression syntax supported is a subset of CPython re module (and actually is a subset of POSIX extended regular expressions).

Supported operators are:

. Match any character. [] Match set of characters. Individual characters and ranges are supported. ^








Counted repetitions ({m,n}), more advanced assertions, named groups, etc. are not supported.



Compile regular expression, return regex object.

ure.match(regex, string)

Match regex against string. Match always happens from starting position in a string.

ure.search(regex, string)

Search regex in a string. Unlike match, this will search string for first position which matches regex (which still may be 0 if regex is anchored).


Flag value, display debug information about compiled expression.

Regex objects

Compiled regular expression. Instances of this class are created using ure.compile().

regex.match(string) regex.search(string) regex.split(string, max_split=-1)

Match objects

Match objects as returned by match() and search() methods.


Only numeric groups are supported.
