Solution

  • If you look at the following (simplified purely for demonstration) example:

    def add_numbers(a, b):
    return a + b  # Returns an integer

result = 5 + add_numbers(3, 7)
print(result)

    If you have a look at the result = 5 + add_numbers(3, 7): this will be interpreted by Python as "run the function 'add_numbers', obtain the returned result and then add it to 5". So, once fully evaluated, that line effectively ends up as:

    result = 5 + 10

    in this example.

    In other words, you can think of it as Python replacing the function call in your code with the returned value of that function, and then performing the addition on those two values.
