I don't know why locals() returns > a copy as opposed to the original, What else can it do? When you enter a function you enter a new namespace. It starts out containing the global names and any parameters to the function then adds new names as they are created plus overrides any global names that get replaced with local versions. It can only do that if it is working on a copy of the global namespace to start with otherwise it would be polluting the global namespace with local functon versions and in a multithreaded environment creating havoc across threads!...

Here panda is the name of a variable whose value is the name of the file
you want to run. Python won't automatically insert the value of a
variable into a string, it thinks you want to Popen a file called
"C:\panda3D-1.2.3\mystuff\panda". Since there is no file with that name,
you get an error.
You can use string formatting to get the name of the file into the
string for Popen(). Try this:
subprocess.Popen("C:\panda3D-1.2.3\mystuff\%s" % panda)
For more info on string formatting:

Re: [Tutor] images in pygame
the tutor mailing list didn't like the zip I attached, so here's the
text of the e-mail I wrote to
Joe without the zip included.
start-
Pygame-specific questions should be posted to the pygame mailing list,
not tutor, probably.

why do you have underscores in the name of this function?
Usually underscores denote functions that are supposed to be private to
a class,
I believe, and this function's not in a class at all!
also,there's no reason to create an 'image_load' variable.
return pygame.image.load( image_obj )
would do just as well.

this strikes me as a very odd way to handle image-loading.
if you're using integers as a reference for a dict why not just use
list indices?
#---
images_path = './img/'
image_names = ['001.png','rockwholescreen.gif']
images = [_loadImages_(images_path,name) for name in image_names]
#---
It took me a minute to figure out what you
were doing, and this way I think your intent is more clear.

I'm guessing you're using a global 'setwinsize' so you don't hard-code
in your resolution.
If you're going to do this, why not just put your globals at the top, so
they're easier to change?
If you have to go hunting through your code for a global you want, it's
just barely
better than hunting through your code to find the place where you need
to change
the hardcoded value.

why not just use setwinsize here also instead of getting the size of the
display surface?
it'll probably be faster.
also, I don't understand why you're doing get_rect on (0,0,640,480)
does get_rect select a subsurface of the image?

if you find yourself appending letters to variable names to distinguish
them you're
probably at the point where you should be using lists.
If someone weren't reading your code very carefully they may get
confused here
and think these variables are the same as the ones above.
Also, later in your code, you might get confused and use the wrong one
of these variables without even realizing and give yourself debugging
headaches.
I don't understand what the * here is doing. it doesn't seem to work
for me.

I'm pretty sure pygame.event.wait() blocks until if gets an event.
Think about this, is this really what you want?
If the user sits there not sending any events, the screen won't update,
but if they move their mouse, you'll get a lot of mousemovement events
and such, and then your program will be rapidly filling the whole screen
with the color (25,110,189) and re-blitting everything even though
nothing moved.

I don't think the escape key raises a pygame.QUIT so if you want the
user to be
able to exit with the escape key, you should put
also, since you imported everything from pygame.locals you don't need a
'pygame.' here
#--
if events.key == K_ESCAPE: break
#-
to get this effect.

here you're not doing dirty-rect animation. you're just updating the
whole screen every time
you get an event.
This is okay for an example but for a real game you'll need to use some
form of
dirty-rect updating method if it needs good performance.
