Question

Write a new recursive function countup that expects a negative argument and counts “up” from that number. Output from running the function should look something like this:

>>> countup(-3)
-3
-2
-1
Blastoff!

I need a script that runs and I can see it and learn why it is working with #comments.

The subject is writing a countup script to blastoff in computer science.
