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

integer, python, string

Solution

If you're really just annoyed at using `try/except`s all over the place, please just write a helper function:

def represents_int(s):
    try: 
        int(s)
    except ValueError:
        return False
    else:
        return True

>>> print(represents_int("+123"))
True
>>> print(represents_int("10.0"))
False

It's going to be WAY more code to exactly cover all the strings that Python considers integers. I say just be pythonic on this one.
