Title of the Skill: Quick Start to ​Engineering (Python): Build Your Own ​Calculator

Assessment: Design and implement a functional basic ​calculator application, demonstrating proficiency in ​handling basic operations, creating a user-friendly ​interface, applying calculation logic, managing error ​handling, and conducting comprehensive testing.

Outcome:

Basic Operations: Implement addition, subtraction, ​multiplication, and division functions.

User Interface: Create a simple GUI (e.g., using Tkinter in ​Python) where users can input numbers and select operations.

Calculation Logic: Write code to perform calculations based ​on user input.

Error Handling: Add basic error handling for invalid inputs ​(e.g., division by zero).

Testing: Test the application to ensure it performs all ​operations correctly.

Hour 1: Implementing Basic Operations

1.1 Introduction to Basic Arithmetic Operations

Overview of addition, subtraction, multiplication, ​and division

Importance of implementing these operations ​accurately

1.2 Implementing Operations in Python

Write functions for each operation

Task: Implement functions for basic arithmetic operations in ​Python.

Hour 2: Creating the User Interface with Tkinter

2.1 Introduction to Tkinter

• Overview of Tkinter: A standard GUI toolkit ​for Python
  
• Importance of GUI for user interaction
  

2.2 Building the Basic GUI Layout

• Create a window with Tkinter
  
• Add buttons and input fields
  

Task: Create a basic Tkinter window with buttons for ​numbers and operations

Hour 3: Implementing Calculation Logic

3.1 Connecting GUI with Calculation Functions

• Bind button clicks to calculation functions
  
• Update the display based on user input
  

3.2 Writing the Calculation Logic

• Implement the logic to handle different ​operations based on button clicks
  

Task: Implement the logic to perform calculations and ​update the GUI based on user input.

Hour 4: Error Handling

4.1 Introduction to Error Handling

• Overview of common errors in calculations: ​Division by zero, invalid input
  
• Importance of handling errors gracefully
  

4.2 Adding Error Handling to the Calculator

• Use try-except blocks to catch and handle ​exceptions
  

Task: Implement error handling to manage invalid inputs and ​operations in your calculator application..

Hour 5: Testing and Review

5.1 Introduction to Testing

• Overview of testing: Importance of ensuring ​correctness and usability
  
• Types of tests: Functional, edge cases
  

5.2 Testing the Calculator Application

• Test all operations: Addition, subtraction, ​multiplication, division
  
• Check error cases: Division by zero, invalid ​input
  

Example Testing Steps:

1. Test basic calculations: 5 + 3, 8 - 2
   
2. Test division: 10 / 2, 5 / 0
   
3. Test multiplication: 4 * 7
   
4. Test clearing the input: C
   
5. Verify results and error messages
   

Task: Test your calculator application thoroughly to ensure ​all operations work correctly and error handling functions as ​expected..

This is a Self- Learning Skill through Video Tutorials. ​However, You may choose a faculty to guide you through ​the skill training. ONE session (two hours) will be handled by ​the faculty (preferably) Friday 8 to 10 p.m. The schedule shall ​be revised in accordance with the availability of the faculty. ​The updated timing will be formally communicated by the ​faculty via email.
