Python Teaching Assistant v1.0.5 Preview Pre-Release 1👨🏻‍💻

🐛 Bug Fixes – Preview v1.0.5 Pre-Release 1

This release focuses on stability and reliability. Four critical issues that affected user experience have been resolved:

---

🔴 Critical Fixes

1. Infinite Loop Freeze – Fixed

The Problem:
Entering while True: pass in practice mode would freeze the entire CLI, forcing users to restart the program.

The Fix:
Added a pre‑execution check that blocks infinite loop patterns (while True and while 1) before they can run.

✅ Result: No more freezes – users see a friendly error message instead.

---

2. exit() Kills Pytalon – Fixed

The Problem:
Typing exit() in practice mode would terminate the entire Pytalon process, losing all session progress.

The Fix:

• Blocked exit() and quit() in the practice namespace with custom functions that raise a catchable exception.
• Added an explicit except SystemExit handler.

✅ Result: exit() now shows: "⚠️ Code attempted to exit. Please don't use exit() in practice." – no crashes.

---

3. Ctrl+C Crash – Fixed

The Problem:
Pressing Ctrl+C anywhere in the program would crash with a full Python traceback, creating a poor user experience.

The Fix:
Wrapped the entire main execution loop in a try/except KeyboardInterrupt block.

✅ Result: Ctrl+C now triggers a graceful exit with: "👋 Sorry, the program got interrupted, it's not your fault. Restart the assistant. Goodbye!"

---

🟡 Medium Priority Fixes

4. Intent Detection False Positives – Fixed

The Problem:
User inputs like "maybe later" were incorrectly treated as exit commands, terminating the session prematurely.

The Fix:

• Moved "maybe later" from EXIT_RESPONSES to UNCERTAIN_RESPONSES.
• Added 'exist' as a recognized exit typo.

✅ Result: "maybe later" now shows: "🤖 No pressure! When you're ready, tell me a topic or type 'show topics'." – session continues.
