The approach of creating function names directly from the "switch"
inputs works so long as the strings are limited to valid Python symbol
name constituents.  For example, strings with spaces or periods in
them would not work, nor strings with unprintable characters or
non-ASCII Unicode.

(I once worked around that by creating alternate names in the class
dictionary, via a metaclass, but that's going a bit far for most
purposes... :-) )
