# This is a Python script created to convert currency.
# The currencies were copper, silver, gold, platinum and electrum
# he values of which were 1, 10, 10, 10, and 5 respectively

# When client was asked what they would like they responded with:

"Output money in the most convenient array of g,s,b (not platinum) if possible
and allow me to take off any amount of currency
Eg we had

114g 3s 2b

I wanted to spend 5 silver

It would automatically do the sum and give me

113 g 8s 2b"
