One way is to transmit the code as a string and compile it on server-side with 
the 'compile' builtin function. Another is to compile it on client-side and 
transmit the resulting code object with the marshal module but there are many 
restrictions on it (specially the fact that the client and server will have 
to run the same python version) so carefully read the docs first. I'd choose 
the first solution, eventually using the pickle module to avoid encoding
