Best Practice to Extract and Remove URLs from Python String

In some comments, there ar some urls in them, if you want to remove them before displaying, you can read this tutorial. In this tutorial, we will introduce you on how to extract and remove urls from a python string.

Import library

import re

Create a python string which contains some urls

text = 'My blog is https://www.tutorialexample.com and not https://tutorialexample.com'

Create a regular regression to match url

pattern=r'(?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:\'".,<>?«»“”‘’]))';

Match urls

match = re.findall(pattern, text)

Print urls

print(match)

The output is:

[('https://www.tutorialexample.com', '', '', '', ''), ('https://tutorialexample.com', '', '', '', '')]

We have extracted urls from python string, then we will remove all of them.

Remove urls from python string
