In -some- ways, "Poser Python" is not the same thing as just plain Python. Poser contains a built-in interpreter for Python and also includes a set of connecting functions that let Python control or sense various aspects of the Poser workspace. (Read and set parameters, save and load files, etc.) So, most scripts written for use in Poser will do nothing at all when activated in a general Python environment, and most scripts you might find in a general Python text or website will do nothing meaningful inside Poser.
