Write a Python script that uses a function to test a given input value and return whether it is enough to cover a purchase of $14.85. Your script should take in the amount due as an argument and continually prompt the user to enter their payment. The function should compare the payment to the cost, print whether it is over or under and by how much, and if it is too much it should then return the difference.

Input string	Expected output of script
Enter a number: 12.89 Enter a number: 14.85 Enter a number: 25.13	That is not enough by 1.96 That is exactly enough There is change due of 10.28

Write a Python script that uses a function to return the amount of change made from a given value based on the following table of coin values:

0	1	2	3	4	5
1	.35	.23	.12	.03	.01

The function should take in the change due as an argument and return a dictionary of the coin values.

Input string	Expected output of script
Enter a value: 9.76	{'1 coin': 9, '.35 coin': 2, '.23 coin': 0, '.12 coin': 0, '.03 coin': 2, '.01 coin': 0}

Write a Python script that will calculate the change due, if any, for a given payment if the total cost is $16.48, based on the following table of coin values. If the payment is made with exact change, no change will be due. If the payment is over the total amount, then the output will be the change due. If the payment is under the total amount, the output will be how much more is needed. Your script should also provide input checking to ensure that only digits are being entered and are in the correct format before doing any calculations.

0	1	2	3	4	5
1	.35	.23	.12	.03	.01

Input string	Expected output of script
Enter your payment: 20.00 Enter your payment: 16.48 Enter your payment: 10.70	change: 3 1 coins, 1 .35 coins, 1 .12 coins, 1 .03 coins, 2 .01 coins, no change due needed: 5 1 coins, 2 .35 coins, 2 .03 coins, 2 .01 coins,
