Syntax errors when running hello world script

hi. My panda3d is correctly installed. However when i write the first page of the hello world script as it is written in the panda 3d manual,a lot of syntax errors occur. My pc runs python 2.5.2. Someone pliz help me out

Panda3D comes with a copy of Python already, so there is no need to install another copy.
This is probably what is wrong, but you should post the error that you get, otherwise it is not possible to know what the problem is for sure.
