How do I create my own module?

To create your own Python module, follow these steps:

Create a Python file: Create a new file with a .py extension. For example, you can name it my_module.py.
Define functions or classes: Inside this file, you can define functions, classes, or variables. For example:
```
# my_module.py

def say_hello():
    print("Hello from my_module!")

def add(a, b):
    return a + b
```
Save the file: Make sure to save the file in a directory where you can access it from your main Python script.

Import the module: In your main Python script, you can import your module using the import statement:

import my_module

my_module.say_hello()  # Output: Hello from my_module!
result = my_module.add(5, 3)
print(result)  # Output: 8

That's it! You've successfully created and used your own Python module.
