Pythonic way to strip all 0's from the front of a string

Question

I have a string that will later be converted with int(). It is three digits, anywhere from 0 to 3 of them might be 0's. How would I strip the 0s from the left side of the string?

Now I'm using string.lstrip('0') but that strips all the 0s and makes the string empty, causing an error.

Answer 1

You can do it like this:

s = str(int(s))

Another alternative is:

s = s.lstrip('0') or '0'

Answer 2

You want str.lstrip() for that. But maybe you should just pass the radix to int().
