How do return values work in Python functions?

In Python, a function can return a value using the return statement. This allows you to send data back to the caller.

Can you show me an example of a function with a return value?

Sure! Here's a simple example:

def add(a, b):
    return a + b

result = add(5, 3)
print(result)  # This will print 8

What happens if a function doesn't have a return statement?

If a function doesn't have a return statement, it returns None by default. For example:

def greet():
    print('Hello!')

result = greet()
print(result)  # This will print None

Can a function return multiple values?

Yes! A function can return multiple values as a tuple. For example:

def get_coordinates():
    return (10, 20)

x, y = get_coordinates()
print(x, y)  # This will print 10 20
