Do you really need to use python?  You can just use the Chimera command "swapaa" to mutate between any of the standard amino acid types.  It does the hard work of calling the right code for you, the same code as the Rotamers tool.  Here is more information on that command and its options:

Most users prefer to use the command and/or graphical interfaces, when possible.  These are more thoroughly documented than the code.  (If you are doing a lot with the python code, it might be a question for chimera-dev at cgl.ucsf.edu instead of chimera-users at cgl.ucsf.edu)
