In Python, modular programming is a common practice to organize code into manageable and reusable components. This often involves creating separate files for different parts of your program and then calling functions defined in one file from another. In this tutorial, we'll explore how to call a function from another file in Python with practical code examples.
Let's start by creating two Python files. For this example, we'll name them main.py and helper.py. The helper.py file will contain the function we want to call from main.py.
Open a terminal or command prompt in the directory where your Python files are located. Then, run the main.py file:
You should see the output:
This simple example demonstrates the basic process of calling a function from another file in Python. You can apply the same principles to more complex programs with multiple modules.
Remember that both files (main.py and helper.py) should be in the same directory or in a directory listed in your Python path for the import statement to work.
Now you know how to call a function from another file in Python, promoting code organization and reusability in your projects.
