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

I have one possibility that doesn't use int at all, and should not raise an exception unless the string does not represent a number

float(number)==float(number)//1

It should work for any kind of string that float accepts, positive, negative, engineering notation...
