Write a python program called make_chocolate.py.
Given 3 positional arguments: the numbers of small bars (1 kilo each), big bars (5 kilos each), and goal kilos of chocolate, return the number of small bars to use if the goal chocolate can be done, assuming we always use big bars before small bars. Otherwise, print out "The goal chocolate cannot be done".
$ ./make_chocolate.py -h
usage: make_chocolate.py [-h] int int int
Make Chocolate
positional arguments:
int the number of small bars
int the number of big bars
int the number of goal kilos
optional arguments:
-h, --help show this help message and exit
$ ./make_chocolate.py 4 1 9
4
./make_chocolate.py 6 2 10
0
$ ./make_chocolate.py 4 1 10
The goal chocolate cannot be done
$ ./make_chocolate.py 1 2 7
The goal chocolate cannot be done
A passing test suite looks like this:
$ make test
