[Python-ideas] Syntactic sugar for checking if a variable is an iterable but not a string?

Many times I want a function parameter that is an iterable but not a string. Usually I do:

try: var.__iter__ except AttributeError: # not an iterable else: try: var.isascii except AttributeError: # put yuour code here

or

from collections.abc import Iterable

if isinstance(var, Iterable) and not isinstance(var, str): # put yuour code here

The first example uses duck typing but it's more verbose. I use the first method in an home-made utility function.

I think it could be interesting to add a syntactic sugar to do this. Maybe a collections.notTextIterable() collections.nonTextIterable() collections.notStrIterable() collections.iterableNotStr() ?
