You need to set up your PATH environment variable to include the python directory. You do this on XP(not so sure about Media Centre!) via the MyComputer->Properties->Advanced->Environment Variables route Once there you need to find the PATH variable and edit it to add the folder where Python lives (look at the properties of the shortcut to Python that you normally use to stat it).

Re: [Tutor] question about importing threads
Thanks, Alan.
Yes, the thing is getting to be a pain to deal with at this size, i am
in-process of splitting out the classes into their own files.
Thanks for your help.

As a general rule of thumb, any Python script (or any programming
language file for that matter!) that gets longer than 4 or 5 hundred
lines should be looked at closely in terms of splitting it into
modules.
There are a few (very few) times where I've seen a thousand line
file that was justified, but nearly any time you get beyond 500
lines you should be splitting things up - especially in high level
languages like Python where the methods/functions tend to be
short anyway.
FWIW
A quick check of the Python standard library shows the
average file size there to be: 459 lines(*) And that's pretty
high IMHO!
There are 19 files over a thousand lines and the biggest file
is over 3000 lines... which seems way too big to me!
But that's out of 188 files...
(*)
Cygwin; Python 2.4
In case you want to repeat for your version I used:
>>> libs = [len(open(f).readlines()) for f in glob('*.py')]
>>> print sum(libs)/len(libs)
>>> print max(libs)
>>> print len([s for s in libs if s>1000])

One thing to watch is that while its easy and tempting to create one file per class it's often better to keep dependant classes together. In other words if class A can only be used together with class B then it is often better to keep A and B in the same module. Anyone who needs B can import the module and anyone who needs A needs B too so it saves them having to import two modules. As in all things in programming a little bit of thought is often better than the first "obvious" strategy. Grady Booch described the above strategy by saying that "the unit of reuse is the category" (which in his OO notation was a set of related classes) and in Python that means the module.

Re: [Tutor] Starting python from a DOS prompt from any directory?
I am learning Python on the office computer which is networked, and am not allowed to change defaults (programmers aren't allowed to do system admin stuff, heck, we can't even move our PC's or monitors). I've got PYTHON installed in d:\python25. So at the DOS prompt, g:\ type in d:\ Then at the d:\ type in CD python25, which changes it to d:\python25. >From there, it's just python mystuff.py to run my programs.

yeah, you know what i totally didn't think about setting the environmental values (yeah Media Center is the same as XP Pro). i guess i should of known that. geeze now i feel like a moron. however, i didn't know about that quick little DOS trick. thanks a lot guys for such a quick response and pointing out the obvious. this has got to be the best and most friendly list ever. happy new year to you all, On 12/31/06, Alan Gauld <[EMAIL PROTECTED]> wrote: "Steve Oldner" <[EMAIL PROTECTED]> wrote > change defaults (programmers aren't allowed to do system > admin stuff, heck, we can't even move our PC's or monitors).

When i come to python i download new 2.5 version and only version for win i could find is SPE-0.8.2.a-wx2.6.1.0-py24 which doesnt work... :-( newer version ist just rpm and i need exe for win... any idea if there will be exe or any more development in SPE cause homepage is not running etc...

Re: [Tutor] XML-RPC data transfers.
Boo bloatware! Don't even mention those... heheh.. I even turn off most the services on my system to keep things clean.. But thats another story.. Going off your thoughts that I'm asking to do something outside the realm of the readers here, is there a better place to ask this kind of oddball stuff? I've looked around and haven't been able to find any support for XML-RPC (might be a good sign to drop it and move to something else?) I'm on the win32 list, and python-list, but I mostly just read those since in my mind most of what I have questions about are noobish things since I'm still trying to get a handle on this language...
