I sometimes find it useful to do:
answers = {True: "go ahead", False: "stop"}
answer = answers[a == "yes"]
This is also sometimes useful when you want to alternate between two values.
values = {'a':'b', 'b':'a'} # define outside loop
while 1:
v = values[v] # alternate between 'a' and 'b'
...
There are limits to this, both the keys and the values need to be hashable.
Cheers,
Ron
