Let's convert a dollar amount into a number of coins. The input will be the total amount, the output will be the number of quarters, dimes, nickles, and pennies. Always break the total into the highest coin value first, resulting in the fewest amount of coins. First convert the dollar amount (1.36) into the total number of pennies (136), then use floor division //, which throws away the remainder. 10/3 is 3.333333, 10//3 is 3.
Enter a dollar amount: 1.36
5 quarters, 1 dime, and 1 penny
Enter a dollar amount: 0.67
2 quarters, 1 dime, 1 nickel, 2 pennies
Instead of hard-coding the coins, store them in a list of tuples. This way you can make custom coins.
coins = [
('half-dollar', 50),
('quarter', 25),
('dime', 10),
('nickel', 5),
('penny', 1)
]
