Regular expressions in Python: module re

Python doesn’t have a literal syntax for regular expressions, as it exists in Perl, JavaScript and Ruby (e.g. /d+/). The re module functions accept a string representing the regular expression. It is recommended to prepend the string with r’…’ to indicate a raw string, avoiding conflicts between Python’s escape sequences (like \b which is the ASCII backspace character) and the regex metacharacters (where \b means word boundary). See an example of using the match function:

import re
re.match(r'\d{4}$', '1234')
