How can I check if a string represents an int, without using try/except?

Question

Is there any way to tell whether a string represents an integer (e.g., \'3\', \'-17\' but not \'3.14\' or \'asf

Answer 1

Uh.. Try this:

def int_check(a):
    if int(a) == a:
        return True
    else:
        return False

This works if you don't put a string that's not a number.

And also (I forgot to put the number check part. ), there is a function checking if the string is a number or not. It is str.isdigit(). Here's an example:

a = 2
a.isdigit()

If you call a.isdigit(), it will return True.
