That’s strange, I just copied your code into a file, and ran ppython with it and it worked with no such problems.
Wait, did you run ppython.exe and then type in ppython pstart.py? Cause what you did then was enter the interactive Python console, and that of course is not valid Python code.
What you have to do, is go into a DOS command prompt, go to the directory where pstart.py is, and type “ppython pstart.py”, or alternatively “C:\Panda3D-1.3.2\python\ppython.exe pstart.py”. Those two should be equivalent if you have a normal Panda installation.
Perhaps you should read some Python tutorials before you continue with Panda, because if you had some basic notions of Python this would’ve been obvious.
