Panda 3D on Windows comes with a special version of python, pre-configured to work correctly with Panda, that python starts with ppython .
Otherwise, you need to add the Panda libraries to your Python path from the Panda installation. There is a file called panda3d.pth that has a path to python, and you can copy this file to C:\[Python Version]\Lib\site-packages .
I do not know what the Panda3d version of python is, but you will need to run this if you do not want to use ppython .
