Returning values

Return a function result and use it in another calculation.

Give a result back

return sends a value back to the caller. Unlike print(), it does not display the value. Store or print the returned value where you call the function.

def add_fee(amount):
    return amount + 2

total = add_fee(10)
print(total)

Output

12

Use more than one parameter

Separate parameters and arguments with commas. return ends the current function call. Here, two inputs produce a value that can be reused.

def cost(price, quantity):
    return price * quantity

subtotal = cost(3, 4)
print(subtotal + 2)

Output

14

Returning values

  1. Track the returned value back to the caller.
  2. Distinguish returning a value from displaying it.

Try it yourself

Return a total

Complete cost(price, quantity) so it returns the product. Keep the supplied call, store its result in total, and display it.
