Final Programming Project Assessment: 400 Points Toward Cour

Final Programming Project Assessment 400 Points Toward Course Grade

Final Programming Project Assessment (400 Points toward Course Grade) Instructions: The following programming problem can be solved by a program that uses three basic tasks-Input Data, Process Data, and Output Results. To process the data, use file, looping, array, decision, accumulating, counting, find min/max and sorting techniques. First, create an MS Word document containing a hierarchy chart to organize your program modules. Second, create a RAPTOR flowchart to solve this problem. Third, create the program with Python.

You MUST use Modular Programming techniques by using Sub Modules in your program. Your "main" module should not be very large. NEVER call "main" from inside your program. Also, do not use "recursion" in this program (submodules that call themselves). You are only allowed to use looping techniques to repeat sections of your submodules.

Problem Statement Ledger's Furniture Store has 10 salespeople. Ledger's wants to produce a combined monthly sales report for all salespeople. Ledger's wants you to write a program that will allow them to enter data in any order, save the unsorted data to a file, and then produce a file in alphabetical order by name of the salespeople. The unsorted output file should be named "sales_unsorted.txt" and the sorted file should be named "sales_sorted.txt". Your unsorted file output should include:

- A list of the salespeople’s names and the monthly sales for each of them.

Your sorted file output should include:

- A list of the salespeople’s name and the monthly sales for each of them.

- At the bottom of the report, list the following:

- The total combined sales for all salespeople.

- The average sales for all salespeople.

- The salesperson with the lowest sales for the month.

- The salesperson with the highest sales for the month.

You must submit the unsorted and sorted files with your RAPTOR program to show that your program ran correctly. Here is your sample test data to use with your program. This is to be typed in as user input.

Salesperson Monthly Sales:

Joan $1525

Bob $1935

Lisa $2550

Tina $1745

Corey $3025

Chummily $1420

Rick $4560

Nancy $2645

Holly $1489

Frank $4450

Your program should handle this input appropriately.

The unsorted file should look similar to this:

Joan Sales: $1525

Bob Sales: $1935

Lisa Sales: $2550

Tina Sales: $1745

Corey Sales: $3025

Chummily Sales: $1420

Rick Sales: $4560

Nancy Sales: $2645

Holly Sales: $1489

Frank Sales: $4450

The sorted file should look similar to this:

Joan Sales: $1525

Bob Sales: $1935

Chummily Sales: $1420

Holly Sales: $1489

Lisa Sales: $2550

Corey Sales: $3025

Tina Sales: $1745

Nancy Sales: $2645

Rick Sales: $4560

Frank Sales: $4450

At the bottom of the report, include:

- Total Sales: $XXXX

- Average Sales: $XXXX

- Salesperson with Lowest Sales: name

- Salesperson with Highest Sales: name

Other Requirements:

- Documentation: Use comments in your final Python program to explain your code.

- Use the "Comments" feature in RAPTOR to document each symbol in the flowchart. Explain data types, formulas, functions, and meanings of symbols.

- Test and debug your program using the sample input data, verify results with a calculator or Excel, and correct any issues.

- Ensure that your program executes correctly and meets all specifications.

- Review this page to confirm all requirements are covered.

- See the Programming Project Rubric for grading principles.

Submission Instructions:

- Submit the following five files:

1. Hierarchy chart in MS Word or PDF

2. RAPTOR flowchart file (named as LastName_FirstInitial_Program_4.rap)

3. Python program file (named as LastName_FirstInitial_Program_4.py)

4. Unsorted output file (sales_unsorted.txt)

5. Sorted output file (sales_sorted.txt)

- Attach files individually (no zipping).

- Resubmissions before the due date are allowed; only the last upload counts.

Paper For Above instruction

This paper presents a comprehensive solution to the programming project assigned by Ledger's Furniture Store, which involves developing a modular Python program for managing sales data of 10 salespeople. The main goals are to input data, process it, and output the sales reports both in unsorted and sorted formats, with accurate calculations of total sales, average, and identifying the lowest and highest performers. The solution emphasizes modular programming techniques, proper documentation, and adherence to the project specifications, including file management, sorting, and reporting.

Introduction

The task involves creating a program that effectively manages sales data for ten salespeople. The program must accept user input in any order, store this data, and then generate two output files: one unsorted and one sorted alphabetically by salesperson name. Additionally, summary statistics such as total sales, average sales, and identifying the top and bottom performers are required. The program's architecture employs modular programming principles, ensuring clarity, maintainability, and adherence to best practices.

Program Design and Structure

The program utilizes a modular design paradigm, dividing tasks into submodules such as data input, data processing, sorting, and output. The main module coordinates these submodules without becoming overly large, thus facilitating readability and testing. In designing the modules, the use of functions in Python replaces break-even monolithic code, aligning with project requirements. The absence of recursion and the restriction to looping constructs further emphasizes the iterative processing approach.

Data Input and Storage

Using a loop, the program prompts the user to enter names and corresponding monthly sales figures. The data is stored in lists, with each entry as a dictionary or a tuple containing name and sales data. The flexible input allows data entry in any order. Data validation can be incorporated to ensure sales figures are numeric and non-negative, which enhances robustness.

File Handling and Output

Once the data input phase is complete, the program writes the unsorted data to the file "sales_unsorted.txt". The output formatting follows the specifications, including labels and dollar signs. Subsequently, the data is sorted alphabetically by salesperson's name using Python's built-in sorting techniques, such as the sorted() function with a key parameter. The sorted data is then written to "sales_sorted.txt", including the summary statistics at the bottom: total sales, average, and the names of salespeople with the lowest and highest sales.

Calculation of Summary Statistics

The program calculates total sales by summing all sales figures, and computes the average by dividing total sales by the number of salespeople. To identify the lowest and highest sales, it searches for the minimum and maximum sales values and retrieves corresponding salesperson names. These calculations are encapsulated within dedicated submodules to ensure clarity and reusability.

Testing and Validation

Testing is conducted using the provided sample data. After inputting the data as described, the program's output files are checked for correctness against expected results. The implementation includes print statements or debugging logs to verify intermediate values such as total, average, and min/max sales. Any discrepancies are debugged and resolved before final submission.

Documentation

Comments in the Python code explain the purpose of variables, functions, and significant blocks of code. The flowchart diagram created in RAPTOR documents the process flow and helps visual understanding. Proper commenting ensures maintainability and clarity for review and grading.

Conclusion

This approach ensures comprehensive coverage of the project requirements through effective modular programming, accurate calculations, and thorough documentation. By meticulously testing and debugging, the program demonstrates adherence to specifications and readiness for real-world application. This solution balances functionality, readability, and modularity, embodying good programming practices.
