Write Python code that asks the use to enter a US dollar amount and then automatically shows how to pay the amount using the smallest number of physical currency. You may only use standard Python, that is$,$ you may NOT use any external libraries, nor use if statements, while nor for loops to answer this question.

For example:

$>>>$ Enter a dollar amount: $420\mathrm{.}69$

$$100$ bills: $4$

$$50$ bills: $0$

$$20$ bills: $1$

$$10$ bills: $0$

$$5$ bills: $0$

$$1$ bills: $0$

quarters: $2$

dimes: $1$

nickels: $1$

pennies: $4$
