re.split() - Splits with Regular Expression

Q

How to split a given string with a regular expression as the delimiter using re.split()?

✍: FYIcenter.com

A

The re.split() function allows you to split a given target string using matches of a given regular expression as the delimiter.

import re
l = re.split(pattern, string, maxsplit=0, flags=0)

Where:
   pattern is the regular expression
   string is the target string
   maxsplit=0 means spliting all matches
   l is the list of sub-strings resulted from the spliting

Here is Python example that shows you how to use the re.findall() function:

>>> import re
>>> s = "Hello perl.org, php.net, and python.org!"
>>> p = "\\W+"
>>> print(p)
\W+
>>> l = re.split(p,s)
>>> print(l)
['Hello', 'perl', 'org', 'php', 'net', 'and', 'python', 'org', '']
