You want to remove everything that is not the "pure" URL? Pretty doable, if you group and remove the initial /https?:\/\//, plus the final part after the question mark.

I loved this kata. I took a lot of time to solve this one, but it was worth it. My code is ugly though. I'll take some time to simplify and refactor it later.

Is it possible to use just a single regular expression to:

1. remove http, https, etc.
2. remove everything after an anchor or parameter
3. extract URL containing a domain name and file name (excluding the file extension)

I spent a lot of time trying to solve this, testing my regex at regex101.com but I can't effectively discriminate between TLDs and file extensions. Has anyone been able to complete the kata using a single regular expression?

I can't believe this issue was reported a year ago and the problem definition is still the same.

Don't you just love how Python does most of the work for you? ^_^

All integers between -1 and 0 inclusive of -1 and 0 are: [-1, 0]
sum(-1, 0) = -1 + 0 = -1
