Testing if Python string variable holds number (int,float) or non-numeric str?

Question

If a Python string variable has had either an integer, floating point number or a non-numeric string placed in it, is there a way to easily test the \"type\" of that value?<

Answer 1

import ast
def type_of_value(var):
    try:
       return type(ast.literal_eval(var))
    except Exception:
       return str

Or, if you only want to check for int, change the third line to block inside try with:

int(var)
return int
