How do I use default arguments in Python?

How do I use default arguments in Python?

You can define default arguments in a function by assigning a value to the parameter in the function definition.

Can you give me an example?

Sure! Here's a simple example:

def greet(name='Guest'):
    return f'Hello, {name}!'

In this case, if you call greet() without an argument, it will return 'Hello, Guest!'.

What if I want to override the default value?

You can simply pass a different value when calling the function. For example, greet('Alice') will return 'Hello, Alice!'.

Are there any limitations to using default arguments?

Yes, default arguments must be defined at the end of the parameter list, and mutable default arguments can lead to unexpected behavior.
