How to use Axes3D from matplotlib directly in standard plot to avoid flake8 error

When using a typical 3D plot:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.gca(projection='3d')

flake8

reports the expected error:

./tools.py:62:9: F401 'mpl_toolkits.mplot3d.Axes3D' imported but unused

I know it can be avoided by using a comment # NOQA

. But is there another way to formulate the projection in the picture so that the Axes3D object is used?

If it is about actually using the import at least once, you can do

ax = fig.gca(projection=Axes3D.name)


as "3d"

is the name of the class Axes3D

by which it is registered in the projection list.
