Type checking: an iterable type that is not a string

Question

To explain better, consider this simple type checker function:

from collections import Iterable
def typecheck(obj):
    return not isinstance(obj, str) and i         


        

Answer 1

I check it with this code and it work fine with Python 2 and 3

from __future__ import unicode_literals
import types
import collections

var = ["a", "b", "c"]
if isinstance(var, collections.Iterable) and \
        not isinstance(var, types.StringTypes):
    return var
