First, import function from file.py:
from file import function
Later, call the function using:
function(a, b)
Note that file is one of Python's core modules, so I suggest you change the filename of file.py to something else.
Note that if you're trying to import functions from a.py to a file called b.py, you will need to make sure that a.py and b.py are in the same directory.

Do not write .py when importing.
Let file_a.py contain some functions inside it:
def f():
return 1
def g():
return 2
To import these functions into file_z.py, do this:
from file_a import f, g

Importing functions from other folders
If you're running run_file.py, then class_file.py can access function_file.py as folder1.function_file. If you're running class_file directly in order to test it, then that won't work, but that's not how you should write tests for your code. More on reddit.com

July 4, 2024How do I call a function defined in another Python file?
Put both files on the same import path (usually the same directory or a package), then use from module import function or import module and call module.function; Python must be able to resolve the module name when you run the entry script.

What does importlib.import_module do?
It is the supported programmatic API around Python’s import machinery: you pass a dotted module name as a string and get a module object back, equivalent to an import statement at runtime without hard-coding the name in source.

Why do I get ModuleNotFoundError when importing my own file?
Usually the current working directory or package layout is wrong, the filename does not match the module name, a parent directory is missing from sys.path, or you run a module inside a package without the -m flag so relative imports break.

Hello. I have a code divided over different files like this:
-run_file
folder1
- function_file
folder2
-class_file
I can easily import functions defined in the function_file into the run_file. However I cannot import functions into the class_file because I somehow need to write a code so that the class_file can "look out" of folder2 and look in to folder1. I looked into the code of a person who had a similar project and there were these 'things':
sys.path.append("..")
dirname = os.path.dirname(__file__)He told me I could do it like this but it did not work for me. Could somebody give me a few hints on how I could achieve this?

r/learnpython on Reddit: importing functions from another file
June 4, 2021 -
Hello,
I have the following file structure (names are just placeholders):
app_dir ---> functions.py ---> function_tests.py
When I import functions at the top of the function_tests.py file, everything works fine.
However, I've lost the docstrings that normally pop up when I start entering a function name, when I use them in function_tests.
Can someone explain this? I am hella hazy on Python importing in general but it's on the to-learn list! For reference, this might be IDE-specific, in which case I am using Spyder.
Thanks :D
