Why doesn't import work in Python?

Question

Python

The question is banal, but I stalled at this point.
There is a main file, and there is a module that contains one function. They are in the same folder. In the main file there is a function call from the module.
It works if from test_function import abc, but it doesn't work if import test_function (I want all subsequent code from the module to be automatically imported into the main file in the future). Am I doing something wrong?

Answer 1

Am I doing something wrong?

Yes

Answer 2

How do you call?
If I remember correctly - in the second case, you need to call through the module - test_function.abc()

Answer 3

from test_function import *

Answer 4

import test_function

test_function.abc()
