User Session Tracker (Log Parsing)

This repository contains the final solution for a critical log parsing challenge from the Google IT Automation with Python Professional Certificate.

🎯 Project Goal

The primary goal was to process raw log entries (login/logout events) to generate an accurate report of all users currently logged into various machines on a network.

💡 Key Skills Demonstrated

• Error & Edge Case Handling: Implemented robust logic to handle invalid sequences (e.g., logouts without prior logins), preventing exceptions like KeyError.
• Data Structure Optimization: Effective use of Python's Sets for efficient tracking of active user sessions.
• OOP/Function Definition: Structured solution using the Event class and dedicated functions (current_users, generate_report).
• Log File Processing: Fundamental skill in IT automation and system administration.

📍📁 Files Info:

• user_session_tracker.ipynb — The main Jupyter Notebook containing the complete code and execution output.
• generate_report.py — (Optional) Command-line script to read a log file and print/save the current-users report.
