I found this code on the web
# Python code to find the URL from an input string
# Using the regular expression
import re
def Find(string):
# findall() has been used
# with valid conditions for urls in string
regex =
r"(?i)\b((?:https?://|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'\".,<>?«»“”‘’]))"
url = re.findall(regex,string)
return [x[0] for x in url]
# Driver Code
string = 'My Profile:
https://auth.geeksforgeeks.org/user/Chinmoy%20Lenka/articles in the portal
of http://www.geeksforgeeks.org/'
print("Urls: ", Find(string))
