How to omit module prefix?

Question

I am very new to python, I have a simple question.

For example

If I do

import A

then I can use A.b(). I am wondering, how to omit A in A.b()?

Answer 1

If you want to use b from module A:

from A import b

If you want to rename it:

from A import b as my_b

If you need several objects:

from A import b, c, d

If you need everything:

from A import *

About the import * option, please do read this post. It's rather short, but tl;dr: do not import everything from a module by from A import *. If you really need everything from the module, or a very big part of its content, prefer the normal import, possibly with renaming:

import numpy as np
import tkinter as tk
