None not None in Excel COM?

[Gonçalo Rodrigues]

Maybe someone can help me out here.

Im using Excel via Python COM and have already run makepy on its type
library.

The problem is the following:

Let sheet be a reference to an Excel worksheet and suppose
sheet.Cells(row, 1) returns None for a given row > 1. The problem is
that if I do

sheet.Cells(row, 1) == None
sheet.Cells(row, 1) is None

both return 0. What am I doing wrong?

Thanx for all the help,
Gonçalo Rodrigues
