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

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

Examples of Ways to Import Functions in Python from Another Files
May 3, 2024 - Finally, double-check the function name to make sure it's spelled correctly and that it's defined in the file you're trying to import from. For example, let's say you want to import the runsqlscript function from the sqlideutils module. Here's how you could do it using the from keyword: from sqlideutils import runsqlscript · And here's how you could do it using the import keyword: import sqlideutils with runsqlscript = sqlideutils.runsqlscript · Organizing your Python code is crucial to make it readable, maintainable, and reusable.

r/learnpython on Reddit: Importing functions from other folders
December 27, 2021 -
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?

Additional scripts do not need to be opened. The streamlined process eliminates possible errors. Learn this step by step with the interactive Computer Science roadmap. For clarity, here are some terms used often when describing import statements: Library: a collection of related modules such as NumPy, Pandas, etc. Module: a file with the ".py" extension; used interchangeably with script

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

Call functions in other files by placing modules where Python can resolve them: same directory as the script you run, or a package tree imported with dotted names from the project root on sys.path.

To import functions from libfunctions.py into main.py, we can use the following import statement: ... To import scripts from parent or sibling directories, we can use package relative imports. First, we must ensure that our directories are recognized as packages by Python, which we can do by creating an empty file named __init__.py in each of them.
