It seems that your problem has been solved, but... just 'cause...

Your second function could easily be written like this:

def InRange(sequence, index):
    try:
        sequence[index]
    except IndexError:
        return 0
    else:
        return 1

(Note that the 'return 1' isn't strictly required to be in an 
else: clause here, but I think that using else, in this case, is 
a clearer expression of intent.)
