A function automatically passes values out of a function when it reaches the end.

Yes, that's correct. In programming, a function can return a value. Here's how it works:

1. A function is a block of reusable code that performs a specific task.

2. When you define a function, you can specify what value it should return. This is done using the return statement.

3. When the function is called during the execution of the program, it performs its task and then returns the specified value.

4. Once a return statement is executed, the function stops executing, and the value is sent back to the part of the program that called the function.

5. If a function doesn't have a return statement, it will automatically return None when it reaches the end.

Here's an example:

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

result = add_numbers(5, 3)
print(result)  # Outputs: 8

In this example, the function add_numbers takes two arguments, adds them together, and then returns the result. When we call the function with the arguments 5 and 3, it returns 8, which is then stored in the variable result and printed out.
