Python-courses-download-Python-courses-s-Python-courses

Exercise 66

Write a Python program that extract the list of all urls from given a string s. Example if s = "You can use google https://www.google.com or facebook https://www.facebook.com" The algorithm returns the list
['https://www.google.com' , 'https://www.facebook.com']

Solution

def extractURL(s):
    # initializing the list of urls:
    listURL = []
    
    # converting the string s into a list
    L = s.split()
    
    for element in L:
        if (element.startswith('https://') or element.startswith('http://')):
            listURL.append(element)
    return listURL

# Teting algorithm
s = "You can use google  http://www.google.com  or facebook https://www.facebook.com"
print(extractURL(s)) # The output is:
# ['http://www.google.com', 'https://www.facebook.com']
