Splitting of group expenses with Python.

How to format your input.txt file

The first line should be the first names of all involved, seperated by a space.

shane maneesh cliff angelo

The following lines are for expenses. This is the format:

[item] [amount] [who paid] [who owes for purchase]

So if Shane paid $25 for an Uber and Angelo, Maneesh, and Cliff all rode, it would look like this:

uber 25 shane shane angelo maneesh cliff

If Cliff paid $260 for dinner that Maneesh and Shane also enjoyed, it would look like this:

dinner 260 cliff cliff maneesh shane

If Cliff paid $100 for something Shane, it would look like this:

thing 100 cliff shane

You can also comment lines using the tilde character

~ This is a comment!

The file should be a .txt file. Look at input.txt for a complete input file example.

How to run

python3 calculate.py input.txt

If you would like to round the values, pass it the following paramaters:

• Nothing does not round
• r to round normally
• ru to round up
• rd to round down

To round up would look like this:

python3 calculate.py input.txt ru

Example input.txt
