Write a function 'swap () ' that takes two numbers as parameters. This function will swap what's currently stored in the numbers and return the two numbers back to its caller. You can add new statements to the swap function but you can't delete or rewrite the existing statements below. def swap (num1, num2): # Insert answer here return(num1, num2) def start(): num1 = int(input("First number: ")) num2 = int(input("second number: ")) num1, num2 = swap (num1, num2) # Numbers are swapped now start ()
