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