How do I use parameters in Python functions?

In Python, parameters are used in function definitions to allow you to pass data into functions. You define them in the function's parentheses.

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

Sure! Here's a simple example:

def greet(name):
    print(f'Hello, {name}!')

You can call this function with a name as an argument.

What happens if I don't provide a parameter when calling the function?

If the parameter is required and you don't provide it, Python will raise a TypeError. You can also set default values for parameters to avoid this.

How do I set default values for parameters?

You can set default values by assigning them in the function definition like this:

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

Now, if you call greet() without an argument, it will use 'Guest'.
