Remove from end of string up to and including some character

[lbtdne]

Hi all,

I'm trying to take some string, stri_ , and iterate through it until I find a particular character. Then, I will update the stri_ to be stri_ with that character and everything after it removed.

#  Working with url_ , a string of any length
url_ = url_[:url_.find(".")]

#  For url_ == "wikipedia.com", url_ should become "wikipedia".
print(url_)  # wikipedia

The above works fine in most cases, however I ran into problems with the below.

#  Working with url_ , a string of any length
url_ = url_[:url_.find(".")]

#  For url_ == "en.wikipedia.com", url_ should become "en.wikipedia".
print(url_)  # en

Is there any way I can do something similar to rstrip(), but instead of removing a single character, remove every character rstrip() checked before it found "." ie. the last "." in the string?

Thanks,

K
