Ginger Beer Machine

ginger beer

Suppose that a machine sells bottles of Ginger Beer for 50 cents and only accepts coins in these denominations: 25 cents, 10 cents, and 5 cents.

In a file called ginger_beer_machine.py, implement a program that prompts the user to insert a coin, one at a time, each time informing the user of the amount due. Once the user has inputted at least 50 cents, output how many cents in change the user is owed. Assume that the user will only input integers, and ignore any integer that isn’t an accepted denomination.

Note

The commandline supports tab completion. You can use tab to complete commands or filenames after typing the first few characters of a command or filename.

Before You Begin

From the root of your repository execute cd src/loops So your current working directory is ...

src/loops $:

Next execute

code ginger_beer_machine.py

to make a file called ginger_beer_machine.py where you’ll write your program.

How to Test

Here’s how to test your code manually:

Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 25 and press Enter. Your program should output:
```
Amount Due: 25
```
and continue prompting the user for coins.
Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 10 and press Enter. Your program should output:
```
Amount Due: 40
```
and continue prompting the user for coins.
Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 5 and press Enter. Your program should output:
```
Amount Due: 45
```
and continue prompting the user for coins.
Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 30 and press Enter. Your program should output:
```
Amount Due: 50
```
because the machine doesn’t accept 30-cent coins! Your program should then continue prompting the user for coins.
Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 25 and press Enter, then type 25 again and press Enter. Your program should halt and display:
```
Change Owed: 0
```
Run your program with python ginger_beer_machine.py. At your Insert Coin: prompt, type 25 and press Enter, then type 10 and press Enter. Type 25 again and press Enter, after which your program should halt and display:
```
Change Owed: 10
```

Pytest

You can execute the below to check your code using pytest from the root directory.

pytest .\tests\loops\test_ginger_beer_machine.py

A green output from running the test means it was successful. A red output means there is a bug in your code that you need to fix.

How to Submit

From github desktop or the command line, commit your changes and push them to your repository.

Codespace terminal or your local terminal.

Note

You will need to have installed git-scm for this to work locally

At the /datatypes $ prompt in your terminal:
