Python has a neat concept for making this easy :^) it is called a class.
class MyFunctions(object):
def funcA(self, param1, param2):
print "FA " + param1 + " " + param2
def funcB(self, param1, param2):
print "FB " + param1 + " " + param2
def funcC(self, param1, param2):
print "FC " + param1 + " " + param2
def defaultFunc(self, *args):
print "Command not recognised"
def doCommand(self, cmd, *args):
return getattr(self, 'func'+cmd, self.defaultFunc)(*args)
functions = MyFunctions()
result = functions.doCommand('A', 'foo', 'bar')
You have to add an extra 'self' argument to each function (or make it a
staticmethod), but you could always use it to store state without resorting
to globals.
