python - How to import module that contains a file in it

Question

I have installed a custom module I created myself for learning. If I do

from my_first_module import test
test.thisprintssomething()

The function will work, but if I do

import my_first_module
test.thisprintssomething()

Python spits out, NameError: name 'test' is not defined. How would I import without using "from"?

EDIT:

I've fixed it myself. I forgot to add an "import test" line to my init.py in my_first_module module.

Answer 1

since you are importing my_first_module you have to tell the code,, test belongs to my_first_module

import my_first_module

my_first_module.test.thisprintssomething()

for more clarification you can have a look at Importing Python Modules

Answer 2

import my_first_module

my_first_module.test.thisprintssomething()
