Fails for the OP's example:
>>> string1 = "ABC 11"
>>> int(string1)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: invalid literal for int(): ABC 11

Again ...
>>> string1.isdigit()
False
If you were desperate to avoid regexes, this works:
>>> max([(d in string1) for d in "0123456789"])
True
... but it's not exactly legible.
