Numeric data question

[terry]

I'm a Python newby, but I have read several books, documentation, 
and email list archives, and I have not found a direct reference 
to how money calculations can be handled in Python.  
Specifically, I'ld like to use a Postgres (or any database) 
numeric data column that represents money with 'normal' Python 
math operators.  I am *very* aware of the floating point 
problems, and know that I must avoid even using floating point 
for accounting applications. 

Would someone kindly either give me a short explaination or point 
me toward an information source.

Thanks in advance,

terry
