Python: How to remove [' and ']?

Question

I want to remove [\' from start and \'] characters from the end of a string.

This is my text:

\"[\'45453656565\']\"
         


        

Answer 1

You could loop over the character filtering if the element is a digit:

>>> number_array =  "['34325235235']"
>>> int(''.join(c for c in number_array if c.isdigit()))
34325235235

This solution works even for both "['34325235235']" and '["34325235235"]' and whatever other combination of number and characters.

You also can import a package and use a regular expresion to get it:

>>> import re
>>> theString = "['34325235235']"
>>> int(re.sub(r'\D', '', theString)) # Optionally parse to int
