Quite a few things.
Your try lines don't have matching excepts....
You have a function definitions in the middle that have
indentation errors.

eg.
       def eight_digit_binary1(message):
           response1 = input(message)
       while len(response1) > 8:
           response1 = input(message)
       return (response1)

should be:

       def eight_digit_binary1(message):
           response1 = input(message)
           while len(response1) > 8:
               response1 = input(message)
           return (response1)

Except that its buggy (what is returned if the user just hits Enter? Or 
types "fabulous"), but at least the indentation is right!

Also, since you never seem to change 'on' anywhere you might as well use 
a while True loop....

It says unexpected indent and the bottom of the code everytime I run it. 
  Thank you
