to call a function from another file in python, you need to import the module containing the function and then use the dot notation to access and call the function. here's a step-by-step tutorial on how to do this:

step 1: create the file containing the function you want to call
create a python file, let's call it `my_functions.py`, and define a function inside it. for example:



step 2: create the file from which you want to call the function
create another python file, let's call it `main.py`, where you will import and call the function from `my_functions.py`.

step 3: import the module and call the function
in `main.py`, import the `my_functions` module using the `import` statement, and call the `greet` function from it:



step 4: run the main file
to run the `main.py` file, open a terminal or command prompt, navigate to the directory where both `main.py` and `my_functions.py` are located, and run the following command:



this will import the `my_functions` module, call the `greet` function with the provided name, and print the returned message.

by following these steps, you can call a function from another file in python. remember to ensure that both files are in the same directory or that python can locate the module in the system path.
