In this assignment you will write programs that use decision structures and can handle exceptions. [MO6.1, MO6.2, MO6.3]

Directions

Part A

The speeding ticket fine policy in Podunskville is $50 plus $5 for each mph over the speed limit plus a penalty of $200 for any speed over 90 mph.

• Write a program that accepts a speed limit and a clocked speed from the user, and either prints a message indicating the speed was legal or prints the amount of the fine, if the speed was illegal.

Part B(the program is below in python which needs to be modified)

• Modify the program you wrote for Programming Assignment 3 (Module 3) to handle the case when the line does not intersect the circle. You should use Pythons exception handling using try/except to catch the error and print out a customized error message.
