Basic Python Script If Statement

I am messing around with this basic Magic 8 Ball program and im trying to make it only allow yes or no questions I am thinking that it will only except questions that have the first word "will" or "do" how can I make a that only allows those to words?

Here is the Script:

import random
import time
print "Welcome to Magic Eight Ball !"
while True:
    def Magic8(a):
        foo = ['Yes', 'No', 'Maybe', 'Doubtful', 'Try Again']
        from random import choice
        print choice(foo)


    a = raw_input("Question: ")
    if a == "exit":
        exit()
    #If Stament here
    print "Determining Your Future..."
    time.sleep(2)
    Magic8(a)

maybe if you have little words you can use elif or or

if a=="exit":
    exit()
elif a=="optionOne":
     doSomething
else:
    print "word not alowed"

Or you can do like this

if a=="exit" or a=="notAllowedWord":
    exit()

You can use str.startswith and pass a tuple of accepted words. 

if a.lower().startswith(("will ", "do ")):
   # Do your magic.

if a.split(None, 1)[0].lower() in {'will', 'do'}:
    print "Determining Your Future..."
    time.sleep(2)
    magic8(a) # function names are usually not capitalized

str.split() splits the sentence on whitespace, str.lower should handle the uppercase.
