PyCharm type hinting weirdness

Question

While working with PyCharm, I am getting the following error: 

Expected 'collections.Iterable', got 'range[int]' instead

This inspection detects type errors in function call expressions. Due to dynamic dispatch and duck typing, this is possible in a limited but useful number of cases. Types of function parameters can be specified in docstrings or in Python 3 function annotations.

for _ in range(x):

This is how I have written the for loop. Is there any other solution?

This looks like a bug in PyCharm. A range object is an iterable, and an Iterable. In 3.4.3:

>>> import collections
>>> x = 3
>>> isinstance(range(x), collections.Iterable)
True

Try reporting the issue to PyCharm people.
