Question

I am reading from an informix database on windows server via python and pyobdc.

Retrieving a row with decimal values I get something like this:

    [(Decimal("0.99"), ), (Decimal("0.0"), ), (Decimal("113.84"), ),.....]

It is no problem to get rid of the Word decimal but I cant figure out how to delete all the braces and ” I dont need so that I can calculate the sum of this list.

What is the best way to do it in python?

Answer 1

You can just calculate sum of Decimal objects, they have __sum__ method.

>>> from decimal import Decimal
>>> a = [(Decimal("0.99"), ), (Decimal("0.0"), ), (Decimal("113.84"), )]
>>> sum(i[0] for i in a) #Because they're in a tuple
Decimal('114.83')
