Lab 14: Coding Lab: Choose your own adventure

Points Possible: 100

Due: Thursday, December 12th

In this lab, you will use your knowledge of Python to solve programming challenges.

Submission:
Submit a Python file for each of the programs, along with any output images saved during execution.

Pair programming

Pair programming is a software development technique in which two programmers work together at one computer. One, the driver, writes code while the other, the navigator, reviews each line of code as it is typed in. The two programmers switch roles frequently.

• This is a group assignment, but you should each turn in your code individually.
• Groups will be assigned at the beginning of lab.
• Rules for groups work:
  • Do not divide and conquer, i.e., do not assign each person an exercise to work on individually.
  • Work together on each exercise and share responsibilities, each person should have a chance to write code.

Instructions:

Solve any TWO of the following problems.

1. Grade Calculator

Write a program that calculates the final grade for a student based on their scores in different categories. Use a dictionary to store category weights (e.g., homework, exams, participation). Your program should:

• Ask the user to input scores for each category.
• Calculate the weighted average and print the final grade as a percentage.
  \(\text{Final Grade} = \sum (\text{Category Weight} \times \text{Category Score})\)

Weights:

category_weights = {"homework": 0.4, "exams": 0.5, "participation": 0.1}

Example Input:

Please enter the homework score: 85
Please enter the exam score: 90
Please enter the participation score: 100

Example Output:

Final Grade: 89.0%

Save the program as grade_calc.py and attach it to the Blackboard lab assignment.

2. Simple Banking System

Write a program to simulate a basic banking system using a dictionary to store account balances. The program should:

1. Allow users to create accounts.
2. Allow users to deposit or withdraw money.
3. Print account details.

Example Interaction:

1. Create Account
2. Deposit
3. Withdraw
4. View Account
5. Exit
Choose an option: 1
Enter account name: Alice
Choose an option: 2
Enter account name: Alice
Enter deposit amount: 100
Choose an option: 4
Account: Alice, Balance: $100
Choose an option: 5

Save the program as simple_bank.py and attach it to the Blackboard lab assignment.

3. Multiplication Table Generator

Write a program that generates a multiplication table for a given range of numbers. The user specifies the starting and ending numbers, and the program displays the table in a formatted grid.

Example Input:

Start: 1
End: 5

Example Output:

    1   2   3   4   5
1   1   2   3   4   5
2   2   4   6   8  10
3   3   6   9  12  15
4   4   8  12  16  20
5   5  10  15  20  25

Save the program as mult_table.py and attach it to the Blackboard lab assignment.

4. Simple Class: Library Book Tracker

Write a class Book that keeps track of books in a library. Each Book should have attributes for the title, author, and whether the book is checked out. Your program should:

1. Allow users to add new books.
2. Allow users to check out or return books.
3. Display all available books.

Example Interaction:

1. Add Book
2. Check Out Book
3. Return Book
4. View All Books
5. Exit
