I would've just tried the type() function first.

# x is variable
#
# python 2.2 or later:
if type(x) is int:
    print "x is an integer variable"
#
# python 2.1 or earlier:
import types
if type(x) == types.IntType:
    print "x is an integer variable"
#
# types.IntType == type(1) ergo:
if type(x) == type(1):
    print "x is an integer variable"

Just because Python doesn't _force_ type checking doesn't mean it
isn't possible.
