There's nothing in your program that actually asks the user for a 
number. You need to use the function input(), like this:

answer = input("Hello puny human, give me a number. ")

If you type (say) 42 then press the Enter key, the variable answer will 
be set to the string "42". You then need to change it to an integer:

number = int(answer) 

or a float:

number = float(answer)

Yes, that's because greetings() prints "Hello" three times, followed 
by "Greetings earthling" once. Then regreet() calls greetings() four 
times in a row, so it prints "Hello" twelve times in total 
and "Greetings earthling" four times.

I hope the above clues will set you on the right track.

We won't do your homework for you, but if you come back with *specific* 
questions, we can help.
