remove semicolon from end of string

I want to remove semicolon from the end of a string in python:

mystring = 'NM_000106.5:c.985+39G>A;c.886C>T;c.1457G>C;'

I tried something like this:

clean_end = mystring[:-1] if mystring.endswith(';') else mystring 

However in this case, mystring.endswith(';') returns False.

Why is this?

>Solution :

You’re not using a regular ;, but a greek question mark (;).

So change the endswith param to the correct one:

mystring.endswith(';')
