Sourcery refactoring id: use-len

Section titled “Sourcery refactoring id: use-len”

Description:

Section titled “Description:”

Replaces sum() with len where appropriate

Before:

Section titled “Before:”
if sum(1 for hat in hats) > 0:
    self.shout("I have hats")

After:

Section titled “After:”
if len(hats) > 0:
    self.shout("I have hats")

Explanation:

Section titled “Explanation:”

This simplification can be made where the sum() call is effectively just determining the length of a sized object. It can only be made where Sourcery can determine that hats supports the __len__() method.
