Unit 4 Programming, BTEC Level 5 HND in Digital Technologies
Assignment - Introduction to Programming with Python
ASSIGNMENT BRIEF
Purpose of this assessment
The purpose of Unit 4: Programming is to provide students with the knowledge and skills required to understand and utilize programming techniques for the development of applications in various programming paradigms. This unit focuses on the strategic and technical aspects of programming within the context of software development, enabling students to address challenges and leverage programming skills to create efficient and effective applications.
Some of the topics covered in this unit include:
Understand the core principles and definitions of Algorithms For Problem Solving, including their characteristics, sources, and applications in solving problems.
Explore how different programming paradigms such as procedural, Object Oriented Programming, and event-driven programming can be utilized to design and develop applications.
Analyse the benefits of using algorithms for improved efficiency, accuracy, and scalability while addressing challenges such as debugging, optimization, and error handling.
Evaluate the role of programming in creating applications that are robust, secure, and user-friendly, with a focus on its potential to streamline processes and enhance functionality.
Learn about methods such as algorithm design, code writing, and debugging, and how these techniques contribute to efficient software development.
Review and compare Integrated Development Environments (IDEs) like Visual Studio and PyCharm, and discuss their use in writing, testing, and debugging code.
Critically assess the importance of following coding standards and best practices in ensuring code readability, maintainability, and collaboration in team-based development environments.
Use industry-leading software and IDEs to implement algorithms, develop applications, and troubleshoot issues, culminating in the successful execution of programs.
Examine the responsibilities of programmers, including the need for continuous learning, problem-solving, and collaboration with other stakeholders in the software development process.
Analyze strategies for ensuring ethical coding practices, including data security, privacy, and the adoption of inclusive design principles in software development.

Role
You are working as a Programmer at Coding Experts. As part of the programming team, your task is working on the following project which requested by a accounting company.
Project: UK Mortgage Affordability and Repayment Calculator Project Scenario
A financial services company has asked Coding Experts to develop a software application that can help users estimate whether a property is affordable and how much a mortgage is likely to cost over time. The client wants a simple but effective system that allows users to enter key financial details and receive clear results based on standard mortgage calculations.
The application should support decision-making by showing whether the mortgage amount appears affordable in relation to household income, while also calculating repayment values that would help users understand the long-term financial commitment.
Project Description
You are tasked with developing a UK Mortgage Affordability and Repayment Calculator for potential home buyers. The system will estimate how much deposit may be needed, whether the property appears affordable based on household income, and how much the mortgage is likely to cost over time.
The calculator will use a simplified affordability rule and a simplified mortgage interest rate rule based on loan-to-value (LTV).
User Inputs
The system should ask the user to enter:
Property value (£)
Number of applicants
Annual income of each applicant (£)
Mortgage term (years)
System Outputs
The system should calculate and display:
Annual Interest Rate (%)
Deposit Amount (£)
Mortgage Amount (£)
Loan-to-Value (LTV) (%)
Estimated Monthly Repayment (£)
Total Repayment (£)
Total Interest Paid (£)
Total Household Income (£)
Estimated Maximum Affordable Mortgage (£)
Affordability Result (Affordable / May Not Be Affordable)
Mortgage Rules and Calculation Guidance
Total Household Income
Add the annual incomes of all applicants:
Total Household Income = Sum of all annual incomes
Estimated Maximum Affordable Mortgage
Use a simplified affordability rule:
Estimated Maximum Affordable Mortgage = Total Household Income × 4.5
Deposit Amount
Use the higher of the following two values:
5% of the property value
the extra amount needed to make the mortgage fit within the affordability limit
Task
Writing a formal report
Chapters will consist of the following sections.
Introduction:
Define what an algorithm is and describe the steps involved in creating an application.
Identify the stages from writing code to executing it.
Examine the process of writing code and highlight the potential challenges encountered.
Assess how an algorithm is implemented in a specific programming language and explain the connection between the written algorithm and its coded version.
Techniques:
Describe the procedural, object-oriented, and event-driven programming paradigms, along with their characteristics and how they are interconnected.
Compare the use of procedural, object-oriented, and event-driven paradigms within the source code of a given application.
Conduct a critical analysis of the source code of an application that incorporates procedural, object-oriented, and event-driven programming paradigms, focusing on its structure and key characteristics.
Software Development:
Develop a program that incorporates an algorithm using an Integrated Development Environment (IDE).
Optimize the written algorithm by leveraging features of the IDE to streamline the development process.
Analyse the advantages of using an IDE for application development compared to not using one.
Discussion:
Describe the debugging process and the tools available within the IDE to support debugging.
Outline the coding standards followed in the program.
Investigate how debugging techniques contribute to creating more secure and reliable applications.
Conclusion:
Analyse the importance of coding standards, explaining their role and benefits for both individual developers and teams.
