Describe the difference between a chained conditional and a nested conditional. Give your own example of each. Do not copy examples from the textbook.

Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional. Do not copy the example from the textbook.

# Chained conditional
# A chained conditional is when you use if/elif/else flow controls and they are all indented to the same depth. No nesting.

# Nested conditional
# A nested conditional is when you use if/elif/else flow controls and the conditionals vary in depth to create a more nuanced sequence of conditionals.

# Nesting is the key differentiator between a Chained Conditional and a Nested Conditional.

Thanks for such amazing work.

Excellent, clear and understanding.

`` def countdown(n):
if n <= 0:
print('Blastoff!')
else:
print(n)
countdown(n-1)

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!

this was so helpful,thanks

Ow wow! You have saved me big time. Great explanation

You guys are really awesome. Thanks alot, it was really helpful.

It really helpful and teachable. I Love it and didn't regret being on this site.

Thanks, it is really helpful.

Yah it has been really helpful thanks
