[Tutor] Are you allowed to shoot camels? [kinda OT]

Unfortunately, that doesn't do the same thing.  In the 'd' case, you get
a print rather than a pass for instance.  It was also just happenstance
that I chose to print on each switch rather than do something like
increment a counter.

Well you can use lambdas. Have them return an expression which you print

after retrieving:
ftable = { 'a' : lambda: 'a',
             'b' : lambda: 'b or c',
             'c' : lambda: 'b or c',
             'd' : lambda: ''}
print ftable.get(var, lambda: 'default case')()

But it would be clearer to store just the expressions:
ftable = { 'a' : 'a',
             'b' : 'b or c',
             'c' : 'b or c',
             'd' : ''}
print ftable.get(var, 'default case')
