creating global variables between modules in python can be useful when you want to share data across different parts of your application. a global variable is accessible from any module that imports it. below is a step-by-step tutorial demonstrating how to create and use global variables across modules.

step 1: create a global variable module

first, you'll need to create a module that defines the global variable. let’s call this module `config.py`.



step 2: create another module to access the global variable

next, create another module that will import the global variable from `config.py`. let's name this module `main.py`.



step 3: modifying the global variable

if you want to modify the global variable in one module and reflect that change in another, you need to follow a specific approach. here’s how to do that:

1. *define a function to modify the global variable in `config.py`.*



2. *modify `main.py` to change the value of the global variable.*



step 4: run the code

1. save both `config.py` and `main.py` in the same directory.
2. open your terminal and navigate to the directory containing the files.
3. run the `main.py` script:



expected output

when you run `main.py`, you should see the following output:



summary

in this tutorial, you learned how to:

create a global variable in one module (`config.py`).
access and print that variable in another module (`main.py`).
modify the global variable using a function defined in the first module.

by following these steps, you can manage global states across different modules in your python applications effectively.
