Python regular expression again - match URL

I have such a regular expression:

 re.compile(r"((https?):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)", re.MULTILINE|re.UNICODE)

But that doesn't include hashbangs (#!). What do I need to change to get it working? I know I can add ! to a group with #@%, etc., but that will select something like

Check this out: http://example.com/something/!!!

And I want to avoid that.

I use this to search for all HTTP and HTTPS URLs. It works like a charm.

URL_PATTERN = "http[s]*\S+"

This is the most complete pattern I use:

URL_PATTERN = r'[A-Za-z0-9]+://[A-Za-z0-9%-_]+(/[A-Za-z0-9%-_])*(#|\\?)[A-Za-z0-9%-_&=]*'

It could be very long but in practice mine works pretty good. Please try this one ((http|https)\:\/\/)?[a-zA-Z0-9\.\/\?\:@\-_=#]+\.([a-zA-Z]){2,6}([a-zA-Z0-9\.\&\/\?\:@\-_=#])*

It matches all of the example below

http://wwww.stackoverflow.com
abc.com

Based on this link, we can use the library validators.

For example:

import validators

valid = validators.url('https://codespeedy.com/')
if valid == True:
    print("URL is valid")
else:
    print("Invalid URL")

This is a common problem. Use default libraries.

For Python, use urlparse.

I'll admit that I'm a little bit worried about an application that requires a regex like that to match URLs. That said, this seems to work for me:

((https?):((//)|(\\\\))+([\w\d:#@%/;$()~_?\+-=\\\.&](#!)?)*)

Don't try to make your own regular expression for matching URLs. Use someone else's who has already solved such problems, like this one.
