Why, can you explain what you think should happen?

Where do you think your code asks for a number?

That seems to be what your code prints so it would appear to be 
reasonable.

Here is your 24

>    for i in range (3):
>        print ('Hello ')
>    print ('Greetings, earthling')

And this repeatedly prints Hello and Greetings Earthling

>    for j in range(4):
>        greetings()

And this calls greetings() repeatedly, so even
more printing of the messages.

> regreet()

And this actually calls regreet() which triggers the whole thing off.

So your code appears to be doing exactly what you told it to do.
Where should the reading of numbers come in?
And what would you do with the numbers when you got them?

You might find the "Talking to the user" topic of my tutorial useful.
