Python - 15: Returning Values From Functions

Functions can send a result back to the rest of your program using return.

Your challenge: Return a number from one function, return text from another, then store and print the results.

Return a result

This function calculates a value and sends it back: return a + b

The returned value can be stored in a variable: result = add_numbers(5, 3)

return is different from print()

print() displays something on the screen. return sends a value back so your program can store it or use it somewhere else.

Return text too

Functions can return strings, numbers, and many other kinds of values.

Try it: Create a function called multiply that returns the result of multiplying two numbers.

Good Python habit: Use return when a function needs to produce a value that other parts of your program can reuse.

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

result = add_numbers(5, 3)

print(result)

def full_name(first, last):
    return first + " " + last

name = full_name("Alex", "Smith")

print(name)

def multiply(a, b):
    return a * b

answer = multiply(4, 6)

print(answer)
