I'm working on the dictionary now,but I came up with this, which uses
a list as the key, and accepts the params to perform the function:

import subprocess as sub
key_list = ['print_something','espeak']

def print_something(params):
	print "%s" % (params)

def espeak(params):
	sub.call(['espeak','%s' % (params)])

key = raw_input("Please enter key: ")

for line in key_list:
	if str(line) == key:
		params = raw_input("Enter Params: ")
		eval("%s('%s')" % (key,params))


I keep getting the function performed in the dict. I'll figure it out
eventually, I know I've done it before, and it might be a lambda
solution...not sure.

But the above could be refined more, it just uses a list, and key/params.
