Python regex capture various url pattern groups

Question

I have dataset containing the string like this and I want to remove the all the urls from the it

http://google.com having trouble finding regex https://google.com for this case http // google com / test some gibberish https // google . com / test / test1 great http.//google.org

Now, I am using this regex pattern to find the all urls:

https?:?\s?\/\/\s?\S+

Now, ideally, it should capture all the urls such as in this case,

• http://google.com

• https://google.com

• http // google com / test

• https // google . com / test / test1

• http.//google.org

but with the regex pattern I have, it is capturing only

• http://google.com

• https://google.com

• http // google

• https // google

You may use

https?[:.]?\s?\/\/(?:\s*[^\/\s.]+)+(?:\s*\.\s*[^\/\s.]+)*(?:\s*\/\s*[^\/\s]+)*

See the regex demo.
