Python Import: import multiple modules in one file

Question

I have many frequently used modules such as os, cv2, numpy,... Every time I need to import them at the beginning of each python file. Now I want to write the import code into one file named all_import.py, and for each python file only import all_import to import all the modules I need.

Is that possible to do that?

Answer 1

Yes, this is possible (but really should not be done). Just set up your files like so:

b.py

import numpy
import scipy

a.py

from b import *

And then use whatever you imported in b.py
