Question

1. Copy the countdown function

def countdown(n):

if n <=

0:
print('Blastoff!')

else:

print(n)

countdown(n-1)

You need to 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!

You need to make a Python program that gets a number using keyboard input. (Remember to use input for Python 3 but raw_input for Python 2.)

If the number is positive, the program should call countdown. If the number is negative, the program should call countup. Choose for yourself which function to call for input of zero.

Provide the following.
