i thought getting into python would be easier or at least more fun... I am
not having much fun at the moment, maybe someone can share some insight.
That will change. In Python it can only be fun.
I have read about the collection types in python. lists, dictionaries,
tuples great stuff. but in XSI i have noticed that sometimes i can use [ ]
brackets when indexing an XSICollection and I can also use ( ) as normal. i
shouldn't do that right?
As Aloys, I'd stick with the XSI SDK convention. I remember someone (I
think it's Guy) had to modify a whole bunch of scripts not so long ago
for this very reason. A new version was released and somehow the []
trick wasn't working anymore in place of collection lookup calls.
Does the extra collection types in python interfere with XSICollections?
Not that I'm aware of.
I have never tried to put a list-dictionary-tuple into an
XSICollection, but the other way around works perfectly. That is, you
can put XSICollections into a list-dictionary-tuple (although you
can't use them as dictionary keys). I do that a lot for my XML
read-write tools. Oh and btw, you can put any COM object (see below)
in the Python native sequence types.
When a method returns an XSICollection is python interpreting that some
other way, maybe into its native collection types?
It's interpreting it as a COM object of "XSICollection" type. With VB
and JS the "COM object" part is irrelevant, but with Python it is
exposed at all times. Anyone correct me if i'm wrong, but any *object*
(ie class instance) provided by the XSI scripting API is a COM object.
Btw, here is a summary of how to setup Python for XSI. I don't know
how much useful it will be for you though, as you are already up and
running:

The relevant part are "How do I hack the pywin32 module?" and "How do
I make "import" work?"
This is intended for people who want to use my larger tools, but it's
useful for those new to Python as well.
Also check the Programming FAQ on XSI Base, lots of tips with Python.
And don't forget xsi-blog.com!
