Alias agreement for imports can reduce costs

This code insight counts one violation each time a one of the following library is not imported with the conventionnal alias. Library -> Alias numpy -> np scipy -> sp pandas -> pd matplotlib -> mpl matplotlib.pyplot -> plt seaborn -> sns datetime -> dt bad
import numpy as my_numpy_import
good
import numpy as np
import numpy

Why you should care

Many well-known libraries have a conventions regarding which alias to use. Choosing a different one will not break the code but makes it less readable and harder to maintain for other developers.

Business Impacts

It is recommended to avoid these in order to ensure the code is more readable and cost effective.
