Today’s goal is to introduce Object-Oriented Programming (OOP) in a simple and practical way.

You will take your Day 04 Log Analyzer script and refactor it using a class-based approach.

You will:

• Create a class to represent a Log Analyzer
• Move related logic into class methods
• Instantiate the class and run the analysis
• Keep the implementation simple and readable

This task helps you understand how DevOps tools are structured internally.

• One Python script (example: log_analyzer_oop.py)
• Script should:
  • Use a class
  • Have at least 2–3 methods
  • Produce the same output as Day 04
• Output visible in terminal (and file if you choose)

• Use:
  • class to group related logic
  • __init__() to initialize values (log file path, counters, etc.)
  • Instance methods for operations (read logs, analyze logs, write summary)
• Keep OOP light and practical
• Do NOT use:
  • Inheritance
  • Abstract classes
  • Advanced OOP patterns
• Follow PEP8 and Python best practices

• Python classes and objects: https://docs.python.org/3/tutorial/classes.html

• When to use OOP (read selectively): https://realpython.com/python3-object-oriented-programming/

• PEP8 – Python Style Guide: https://peps.python.org/pep-0008/

• Your Day 04 Log Analyzer script

In real DevOps work:

• Automation scripts grow into tools
• Tools need structure to stay maintainable
• OOP helps group logic, state, and behavior together

Most internal DevOps tools and platforms are written using simple, practical OOP, not complex theory.

1. Add your OOP-based script inside the day-05 folder
2. Ensure the script runs successfully
3. Verify output matches Day 04 behavior
4. Commit and push your changes to your fork

Share your progress on LinkedIn:

• Post a small snippet showing your class definition
• Mention how OOP improved code structure
• Write 2–3 lines on what you learned today

Optional:

• Tag TrainWithShubham or Shubham Londhe
• Use hashtags: #PythonForDevOps #TrainWithShubham #DevOpsKaJosh (Helps me to filter and engage)
