This program is designed to manage and control access to various rooms for different members. It provides an interface for users to perform the following tasks:
- Check which members have access to a specific room.
- Identify the rooms that a specific member cannot access.
- Add a new member along with their room access permissions.
User-Friendly Interface: The program uses a text-based menu system to guide users through different functionalities. Dynamic Member Management: Users can easily add new members and assign them room permissions. Access Control Queries: Users can check which members have access to specific rooms or determine restricted rooms for a particular member.
-
Data Structures Dictionary: The members_access dictionary maps member names to the set of rooms they can access. Set: The rooms variable is a set containing all rooms. This allows efficient membership checks and set operations like difference.
-
Input Validation User inputs are validated to ensure correctness before performing operations. For example: Ensuring the room name or member name is valid. Handling cases where inputs are empty or invalid.
-
Functional Programming The program is modular, with distinct functions for each operation: accessible(): Checks which members can access a specific room. not_accessible(): Lists rooms a member cannot access. new_member(): Adds a new member and their permissions.
-
Recursive Function Calls The program uses recursion to restart a function if the user input is invalid, ensuring a smooth user experience.
-
Dynamic Dictionary Updates The program allows for adding new members dynamically by updating the members_access dictionary.
-
Set Operations The program uses set operations to compute differences between accessible and total rooms.
Run the Program: Execute the script in a Python environment. Choose an Option: [1] Check which members have access to a specific room. [2] Identify rooms a member cannot access. [3] Add a new member and assign their room permissions. [4] Exit the program. Follow Prompts: Input the required information when prompted. Repeat: After completing an operation, the menu will reappear for additional actions. Example Scenarios Checking Room Access:
Input: room2 Output: "room2 can be accessed by ['Alice', 'Bob']." Finding Inaccessible Rooms:
Input: Charlie Output: "Charlie cannot enter {'room2', 'room4'}" Adding a New Member:
Input: Member Name: Eve Accessible Rooms: room3,room4 Output: "Eve now has access to ['room3', 'room4']"
Add persistent storage to save member data between program runs. Implement a graphical user interface (GUI) for a more interactive experience. Provide error messages for invalid room names or members more explicitly.
