Panda3d won't work on cmd prompt

my cmd prompt tells me:

“ppython is not recognized as an internal or external command, operable program or batch file.”

whenever i try to run:

“ppython pandatutorial.py”

how can i run panda3d from cmd prompt :question:

First, don’t go around posting “help” posts on other threads. You will just annoy people and are even less likely to get a reply then.

This error is explained at the second page of the manual:
panda3d.org/manual/index.php/I … in_Windows

Thank you so much.
