feature: add hotel management system

[Chirantan112]

Summary

This PR implements the Python-based Hotel Management System Starter as proposed in issue #204. It provides a structured, medium-difficulty learning project for the starter_code library, focusing on real-world logic like room inventory management and guest data validation.

Closes #204

Type of Change

• Feature — adds a new educational project to the starter_code library
• Documentation — includes structured learning goals and a step-by-step roadmap
• Style — clean, PEP8 compliant code formatting

What Was Changed

File	Change made
starter_code/hotel_management.py	Implementation of a 40-room management system with tiered pricing, booking validation, and search filters.

Key Features Implemented

• Interactive CLI Interface: A command-line menu system for easy navigation and user interaction.
• Dynamic Room Inventory: Automatically initializes 40 rooms across Standard, Deluxe, and Suite tiers.
• State Management: Utilizes nested dictionaries to track availability and guest details in real-time.
• Validation Logic: * Validates 10-digit phone numbers for guest registration.
  • Restricts bookings to a maximum of 30 days to prevent business logic errors.
• Filter Engine: Users can search for available rooms specifically by their category type.

How to Test This PR

1. Navigate to the directory: cd starter_code
2. Run the script: python hotel_management.py
3. Verify Business Rules:
   • Test Case 1: Attempt to book a room with an 8-digit phone number (Expected: Error).
   • Test Case 2: Attempt to book a room for 31+ days (Expected: Blocked).
   • Test Case 3: Verify the total bill calculation accurately reflects the nightly rate for the selected category.

Self-Review Checklist

• I have read CONTRIBUTING.md and followed all guidelines.
• My code follows the repository's structured comment format (Header, Goals, Roadmap).
• I have tested the script locally in PowerShell on Windows.
• I have run flake8 . locally and fixed any linting errors.
• I have removed all unnecessary print() debug statements.

Notes for Reviewer

This PR successfully fulfills the requirements outlined in the project proposal (#204). The code is modular and follows the educational style of the existing grade_manager.py to ensure consistency for new contributors.

Good contribution overall. The Hotel Management System project is a useful addition to DevPath and fits well within the repository’s educational/project-learning goals.

The project structure, roadmap, features, and starter code organization are all well scoped for beginners/intermediate learners practicing data management and application logic concepts.

The PR is clean, properly linked to the issue, and avoids unrelated modifications.

Minor future suggestion: slightly clarify the intended implementation type (CLI/web/GUI) in the description and ensure the starter template remains beginner-friendly rather than overly complete.

Approved for merge.

Hi @komalharshita, thank you for the approval! I noticed that the CI checks were failing due to a universal bug in tests/test_basic.py (the test_health_check is missing a required argument).

I have raised Issue #344 to document this and submitted PR #345 to fix it. Once the test fix is merged, the checks for this project will pass. I've also updated the project description to clarify that this is a CLI-based implementation as suggested!

[Chirantan112]

Hi @komalharshita, I've updated the file header and description to clarify this is a CLI implementation as suggested. Thank you for the approval!"

[Chirantan112]

Hi @komalharshita, sorry for the confusion! My recent push dismissed your previous approval. Could you please take a quick look and re-approve if everything looks good?"

[komalharshita]

Thanks for the contribution — this is a genuinely solid beginner-to-intermediate CLI project idea, and I appreciate the effort put into:

• documentation
• learning goals
• validation handling
• menu structure
• feature completeness

The project is educationally valuable and much more complete than many basic starter submissions.

However, before this can be merged into DevPath’s curated starter-project dataset, there are several important improvements needed.

Main concerns

• The file formatting/style is currently inconsistent and needs cleanup before merge.
• The room state is stored using index-based lists ([type, price, status, guest]), which becomes difficult to maintain and read. A dictionary/object-based structure would be much cleaner and more extensible.
• The project relies heavily on mutable global state, which makes scaling/testing harder.
• There is no persistence layer, so all bookings disappear after restart — this should either be documented clearly or improved.
• UI/input handling and business logic are tightly coupled throughout the file.
• No automated tests or sample validation flows are included.

Requested improvements

• Clean and format the entire file consistently
• Replace list-based room structures with dictionaries
• Improve code organization/readability
• Add notes about persistence limitations
• Optionally include sample test flows or usage examples

The project concept itself is good, but the implementation needs another refinement pass before merge consideration.

Refactor Complete: Dictionary-Based Implementation

I have updated the project based on the feedback to ensure better code quality and alignment with DevPath standards.

Key Updates:

• Data Structure: Migrated from list-based room storage to nested dictionaries. This removes reliance on index numbers and improves data clarity.
• Key-Based Access: All functions (booking, searching, and viewing details) now use descriptive keys (e.g., ["status"], ["type"]) for more robust logic.
• Documentation: * Added a persistence disclaimer to the roadmap and system shutdown message.
  • Included a Manual Validation Flow at the bottom of the script for easier verification.
• Clean Code: Standardized formatting and removed redundant comments/logic.

Ready for a re-review!
