something like:

m = int(obj + 0) # May raise TypeError.
if obj != m:
raise ValueError('expected an integer but got %r' % obj)
is a really awkward way to test if something's an integer, and checking
types in general is usually a sign of larger flaws in laying out useful
code.
What the best way to test if something's an integer?
try:
whatever_you_want(supposed_integer)
except ValueError:
print("Oops, that wasn't an integer! Please try again")
That's usually the best way...
