I see a couple of people have mentioned using a dictionary. If the value that
you are switching on is a string, or could be made into one, you can use a
variant of the command dispatch pattern.
class MyCommandDispatcher(object):
def do_a(self):
# do stuff
def do_b(self):
# do stuff
def do_5(self):
# do stuff
def default(self):
# do stuff
def switch(self, option):
getattr(self, 'do_' + str(option), self.default)()
d = MyCommandDispatcher()
d.switch('a')
d.switch(5)
This isn't _much_ more coding than using the dictionary method, and is pretty
readable. This is also a common pattern in python.
