What are some examples of using arguments in Python functions?

Can you give me some examples of how to use arguments in Python functions?

Sure! In Python, you can define functions with positional arguments, keyword arguments, and default values. For example:

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

This function takes one positional argument, name.

What about keyword arguments?

Great question! Keyword arguments allow you to pass arguments by name. For example:

def introduce(name, age):
    return f'My name is {name} and I am {age} years old.'

You can call it like this: introduce(age=30, name='Alice').

Can you explain default arguments?

Absolutely! Default arguments let you set a default value for a parameter. For instance:

def power(base, exponent=2):
    return base ** exponent

Here, if you call power(3), it will return 9, using the default exponent of 2.

What about variable-length arguments?

Variable-length arguments allow you to pass a variable number of arguments. You can use *args for non-keyword arguments and **kwargs for keyword arguments. For example:

def add_numbers(*args):
    return sum(args)

You can call it with any number of arguments like add_numbers(1, 2, 3).
