Using a dictionary to select function to execute

Question

I am trying to use functional programming to create a dictionary containing a key and a function to execute:

myDict={}
myItems=(\"P1\",\"P2\",\"P3\",....\"         


        

Answer 1

# index dictionary by list of key names

def fn1():
    print "One"

def fn2():
    print "Two"

def fn3():
    print "Three"

fndict = {"A": fn1, "B": fn2, "C": fn3}

keynames = ["A", "B", "C"]

fndict[keynames[1]]()

# keynames[1] = "B", so output of this code is

# Two
