class __getitem__ when item is not a sequence ???

Sorry for the vague subject. Not sure what the right terminology is. How can I use an instance's data by reference to the instance name, not the instance attribute? OK the question is probably really poor but hopefully an example will make it clear. > x=1 > type(x) > x.__add__(1) 2 > print x 1 >

tricky(?) win32com question - Mark Hammond or other experts please.

OK, I've asked this earlier this week with no response. Since then I've also received a suggestion from the app developers but that failed with the same type error problem. Hopefully Mark Hammond or other experts can offer a suggestion as to how to get around this problem. I'm foolish enough to thi

How does python handle VBS "Nothing" keyword

I'm writing a python script using win32com to call a 3rd party program via its VBS based API. In VBS a query to get some plot data goes like this: Plot.QueryBegin datacode, Nothing What is this in python? Plot.QueryBegin(datacode, None) does not work. I get a type mismatch error as follows: co

Re: win32com problem - Problem Solved

Problem solved. Turns out it was a problem of mistranslating VBS code to Python. The PYTHON line "print str(tet)" casts tet to a string and prints. This is what I thought the VBS line "Str = Tet.ConvertToString()" was doing. But of course "ConvertToString()" is a method of a Tet instance. So in p

win32com problem

I'm interacting with a third party application using python and com. However having problems and don't know what to look at next to resolve the issue. The app. can be driven by VBS. The following VBS code works: Set Synergy = CreateObject("synergy.Synergy") Synergy.OpenProject "D:/temp/project.mp

Re: win32com Excel bug?

yth (Yes That Helped). You know how it goes, I thought I'd already tried to include all arguments. Obviously I didn't, or stuffed it up in some other way. Also some confusion about the meaning of "required" and "default". The doc explains these arguments as required, but some have defaults. I gues

win32com Excel bug?

I'm driving Excel from python, largely successfully. Now I'm trying to add errorbars to XY scatter plots. Keep getting a com_error. Can't track down the problem. I modified a simple example to duplicate the problem. Thanks to Mathieu Fenniak http://www.stompstompstomp.com/weblog/entries/67/ for th
