In this unit, we explored the overview of the Conditionals and Recursion, which are the prime requirements for the decision control process in a program. Before completing this assignment, review the reading material below:
Think Python: How to think like a computer scientist Chapter 5 – Conditionals and recursion
Q 1. The following is the countdown function copied from Section 5.8 of your textbook.
def countdown(n):
if n >> countup(-3)
-3
-2
-1
Blastoff!
Write 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 (countdown or countup) for input of zero.
Provide the following.
The code of your program.
Respective output for the following inputs: a positive number, a negative number, and zero.
An explanation of your choice for what to call for input of zero.
Q 2: You are developing a program that performs a division operation on two numbers provided by the user. However, there is a situation where a runtime error can occur due to a division by zero. To help junior developers learn about error handling in expressions and conditions, you want to create a program deliberately containing this error and guide them in diagnosing and fixing it.
Instructions:
Create a Python program that prompts the user to enter two numbers.
Implement a division operation on the entered numbers.
Introduce a condition that raises a runtime error if the second number is zero.
Provide an error message that clearly indicates the cause of the error.
Guide the junior developers in identifying the error message and implementing error handling techniques to handle the division by zero scenario.
Questions:
Provide a code demonstrating how to handle the division by zero error.
Output demonstrating the runtime error, including the error message.
Explain the significance of error handling in expressions or conditions, using the division by zero scenario as an example. Discuss the potential impact of not handling this error in a program.
Please provide detailed explanations and code snippets to guide the junior developers in understanding and addressing the division by zero error in Python programs.
Submission Instructions:
Submit the solutions to both questions in one document.
The code and its output must be explained technically. The explanation can be provided before or after the code. The descriptive part of your response must be at least 200 words.
Make sure your submission is double-spaced, using Times New Roman, 12-point font, with 1” margins.
Use sources to support your arguments. Use high-quality, credible, relevant sources to develop ideas that are appropriate for the discipline and genre of the writing.
Use APA citations and references to support your work. Add a reference list at the end of the submission. For assistance with APA formatting, view Learning Resource Center: Academic Writing.
Your submission should be clearly written, concise, and well organized, and free of spelling and grammar errors. The grading will be based on the quality of your analysis, accurate solution of the problem and the quality of your writing.
