[Tutor] apply() vs. the extended call syntax

[Tim Johnson]

Frequently I use a function dispatch approach like this:
funcs = {"key1":func1,"key2":func2}

## and call one of those functions with a key value
## as follows
funcs[key](some,fixed,number,of,arguments)

Less frequently, I might want to dispatch functions with variable
numbers of arguments.

Follows is an illustrative (hopefully) REPL session
## define a couple of simple function
def test_apply(one,two): print(str(one) + " " + str(two))
def func_two(): print("I don't have an argument!")

## define references to one or more functions and argument lists
## of variable lengths

func_D = {"key1":(test_apply,("one","two")), "key2":(func_two,())}

## give a key some value
k = "key1"

## Use the deprecated apply() function first
apply(*func_D[k])
one two  ## yup, that's what I was looking for!

## Now use the extended call syntax
func_D[k][0](*func_D[k][1])
one two 
## also what I was looking for, but yuck!

Is there a cleaner way to do this? using apply()
looks so much simpler, but I understand it is not even available in
py 3 ....

thanks
