Conversion to Python

I tried to preserve as much of the original layout and flow of the code as possible. However I did use quasi enumerated types for the Fort numbers and Fur types. I think this was certainly a change for the better, and makes the code much easier to read.

I program in many different languages on a daily basis. Most languages require brackets around expressions, so I just cannot bring myself to write an expression without brackets. IMHO it makes the code easier to study, but it does contravene the Python PEP-8 Style guide.

Interestingly the code seems to have a bug around the prices of Fox Furs. The commodity-rate for these is stored in the variable D1, however some paths through the code do not set this price. So there was a chance of using this uninitialised, or whatever the previous loop set. I don't think this was the original authors intent. So I preserved the original flow of the code (using the previous D1 value), but also catching the uninitialised path, and assigning a "best guess" value.
