<s>[INST] How do I remove a substring from the end of a string in Python? I have the following code:
url = 'abcdc.com'
print(url.strip('.com'))

I expected: abcdc
I got: abcd
Now I do 
url.rsplit('.com', 1)

Is there a better way?
 [/INST] You could do this:
url = 'abcdc.com'
if url.endswith('.com'):
    url = url[:-4]

Or using regular expressions:
import re
url = 'abcdc.com'
url = re.sub('\.com$', '', url)
