When should I use optional parameters in functions?

What are optional parameters in functions?

Optional parameters allow you to define functions that can be called with fewer arguments than defined, providing flexibility.

Can you give me an example of a function with optional parameters?

Sure! In Python, you can define a function like this: def greet(name, greeting='Hello'):. Here, 'greeting' is optional.

When should I use optional parameters?

Use optional parameters when you want to provide default values or when the parameter is not always necessary for the function to work.

Are there any downsides to using optional parameters?

Yes, overusing them can make your functions harder to understand and maintain, especially if there are many optional parameters.
