Not particularly. I come from C and C++, which have switch...case
statements, and it isn't a big deal for them to be missing. Case
statements are realy nothing more than glorified repeated if...else
if... statements, and really don't have any more power (in fact, in C
and C++, case statements have less).
If you're really doing something where there would potentially be many,
many if...else if... clauses, then a better approach in Python would be
to use a dictionary whose keys are the case statements and whose values
are the data to retrieve or the function to call. This is syntactically
a lot cleaner and allows for in-code modification of the transition
table.
