How to remove leading and trailing zeros in a string? Python

Question

I have several alphanumeric strings like these

listOfNum = [\'000231512-n\',\'1209123100000-n00000\',\'alphanumeric0000\', \'000alphanumeric\']

Answer 1

Assuming you have other data types (and not only string) in your list try this. This removes trailing and leading zeros from strings and leaves other data types untouched. This also handles the special case s = '0'

e.g

a = ['001', '200', 'akdl00', 200, 100, '0']

b = [(lambda x: x.strip('0') if isinstance(x,str) and len(x) != 1 else x)(x) for x in a]

b
>>>['1', '2', 'akdl', 200, 100, '0']
