Prerequisite : Pattern matching with Regular Expression
In this article, we will need to accept a string and we need to check if the string contains any URL in it. If the URL is present in the string, we will say URL’s been found or not and print the respective URL present in the string. We will use the concept of Regular Expression of Python to solve the problem.
Input : string = 'My Profile: https://auth.geeksforgeeks.org/user/Chinmoy%20Lenka/articles in the portal of http://www.geeksforgeeks.org/' Output : URLs : ['https://auth.geeksforgeeks.org/user/Chinmoy%20Lenka/articles', 'http://www.geeksforgeeks.org/'] Input : string = 'I am a blogger at https://geeksforgeeks.org' Output : URL : ['https://geeksforgeeks.org']
To find the URLs in a given string we have used the findall() function from the regular expression module of Python. This return all non-overlapping matches of pattern in string, as a list of strings. The string is scanned left-to-right, and matches are returned in the order found.
