Program Plan Intro
Exception:
- • It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the
program ’s commands. - • Exception handling is a
mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. - • An advantage of exception handling is to maintain a flow of the program.
- • An exception can be handled using “try” and “catch” block.

3. RetailItem Exceptions Programming Challenge 4 of Chapter 6 required you to write a RetailItem class that holds data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand.
Demonstrate the exception classes in a program.

For each method, you will also be required to create docstring as follows:
/**
* @param String as args
* @return Termination code as int, 0 for normal, anything else is error condition
* @throws Nothing is implemented

Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info."

The starter program below is expected to compute the reciprocal of all the numbers in a list. Fix the starter program to safely catch and handle incorrect divisions accordingly. If an exception occurs, catch the exception and print the exception. Your output should match the expected output below. Expected output The reciprocal of 1 is 1.0 The reciprocal of 2.5 is 0.4 The reciprocal of -6 is -0.17 division by zero The reciprocal of 0.4 is 2.5 The reciprocal of -0.17 is -5.88 unsupported operand type(s) for /: 'int' and 'str' The reciprocal of 3.14 is 0.32 type complex doesn't define __round__ method The reciprocal of 3.141592653589793 is 0.32 Here is the code from the starter file we are required to use: import math numbers = [1, 5 / 2, -6, 0, 0.4, -0.17, 'pi', 3.14, 2-6j, math.pi] for n in numbers: reciprocal = 1 / n print(f"The reciprocal of {n} is {round(reciprocal, 2)}")arrow_forward
