HELP!

I am trying to figure out how to run the first program in the tutorial.
It says that I am supposed to:

"create a text file and save it with the .py extension. PYPE and IDLE are Python-specific text-editors, but any text editor will work. Enter the following text into your Python file:

import direct.directbase.DirectStart
run()

To run your program, type this at the command prompt:

ppython filename.py"

So where am I supposed to put this text file?
Which command prompt am I supposed to run this at?

I installed python, and then installed panda3d, taking the default everything.

I have WinXP

So where am I supposed to put this text file?

For example, you could put it here:

C:\ChickenTastesGood\MyProgram.py

But really, anywhere. Much like you can put a word processing document in any folder, you can put a panda program in any folder.

Which command prompt am I supposed to run this at?

Command prompt is a program included with Windows. On my computer, you’ll find it in:

Start Menu–>Accessories–>Command Prompt

This program pops up a prompt, where you can type commands. To run your program, you’d type the command to switch to the appropriate folder, then type the ppython command:

C:\Windows> cd \ChickenTastesGood
C:\ChickenTastesGood> ppython MyProgram.py
