I need to replace https://www. , http://www. , http:// and https:// using Python3 regex for the below inputs;
Input:
https://www.example.com/
http://www.example.com/
https://example.com/
http://example.com/
Required output :
example.com
Can anyone help me please since I am a beginner in Python.
import re
string = "http://www.example.com"
pat = re.compile("https?://www.")
print(len(string))
val = pat.match(string)
if not val is None:
print(string[val.end():])
else:
print("no match")
should work for you.if you want to start understanding re stands for Regular Expression in python and end returns index of the last match.
val is None if there is no match.
s is an optional character that may appear once.
https? should do (optional single character)
split('/')[0] on the resulting string. I guess.[www]? for wwwThanks a lot for your suggestions and help. After going through the regex tutorials I managed to write the below code which gives me the expected result.
import re
domain = input("Enter the domain name : ")
stripped =
re.sub(r'https://www\.|http://www\.|https://www|http://|https://|www\.', "",
domain).strip('/')
print(stripped)
>>> import re
>>> m = re.search('example.com', a)
>>> if m:
... print(m.group(0))
where a is the text variable
https://example.com/test/?'https://www.example.com/'.split('//')[1].split('/')[0]or look intourllib.parse.
