[Chimera-users] python scripts

Dear Madam/Sir I am new to Chimera and this forum so I apologize in advance if I my question is inappropriate. I want to start writing python scripts such that I can run the script and the color code, orientation, etc of the molecule opened can be automated. Do you know of any good tutorials that teach what commands are available to use in python for chimera and how to run some basic python scripts in chimera? I have figured out enough to open the Python Shell in Chimera, but that is all. An example python script would be helpful. Thanks everyone, Chris Lau
