PYTHON CODE 1. Use append () and pop () to add the number 4 and 5 to stack and to take out the last three numbers from stack. Print out the result in the order you get from pop (). stack = [1, 2, 3] 2. Create a function that calculates change. Write a function return_change (payment, price) that returns a list of coins to be paid back. Th coins are 1, 5, 10 and 20 euros and we want to pay back with few coins as possible. We would rather use one 20 euros than two 10 euros. Do not use print () or input (). Example: >>> return_change(50, 40) [10] >>> return_change(40, 23) [10, 5, 1, 1]
