replace

replace(string: str, pattern: str, replace: str, count=0) -> str

Return the string obtained by replacing the leftmost non-overlapping occurrences of the pattern in string by the replacement.

import regex

regex_replace = regex.replace(regex_source, ",", "|")

match

match(string: str, pattern: str) -> bool

Try to apply the pattern at the start of the string, returning a bool value True if any match was found, or False if no match was found.

import regex

regex_result = regex.match("192.168.0.1", "^(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|[1-9])\\."+"(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)\\."+"(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)\\."+"(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)$")

compile

compile(pattern: str) -> bool

Compile a regular expression pattern, returning a bool value denoting whether the pattern is valid.

import regex

regex_compile = regex.compile("$^")

findall

findall(string: str, pattern: str) -> List[str]

Return a list of all non-overlapping matches in the string.

import regex

regex_find_all = regex.findall("aaaa", "a")

search

search(string: str, pattern: str) -> bool

Scan through string looking for a match to the pattern, returning a bool value True if any match was found, or False if no match was found.

import regex

regex_search = regex.search("aaaa", "a")

split

split(string: str, pattern: str, maxsplit=0) -> List[str]

Return a list composed of words from the string, splitting up to a maximum of maxsplit times using pattern as the separator.

import regex

regex_split = regex.split(regex_source, ",")
