python - Version agnotstic checking if a variable is an integer? -

in python 2.6 , 2.7 use

isinstance(variable, (int, long)) 

in python 3x ints , longs merged.

isinstance(variable, int) 

is there clean version agnostic way of testing if variable integer in python?

from 2.6 can use numbers.integral:

if isinstance(var, numbers.integral):     pass # whatever
