Importing naming collisions can cause risks

This code insight Counts one violation each time a name collision  is encountered: pattern 1: from xxx import yyy from zzz import yyy pattern 2: from xxx import yyy as zzz from aaa import bbb as zzz pattern 3: import yyy as zzz import bbb as zzz bad

from numpy import floor
from numpy import array
from math import floor # Overwrites already imported floor function

good

from numpy import floor as np_floor
from numpy import array as np_array
from math import floor # Does no longer overload numpy's floor function

 

Why you should care

As the last import will overload previous one's, importing two objects with the same name can lead to unpredictable or even catastrophic results.
