This project simulates an advanced package manager in Python, resembling functionalities of popular package managers like npm or pip. It includes features like dependency resolution, version control, and a sample Python application to demonstrate its usage. I would like to extend its benefits further.

• Dependency Resolution: Handles complex dependency trees for package installation.
• Version Management: Supports installing specific versions of packages.
• Package Database: Maintains a local JSON file to track installed packages and their versions.
• Simulated Remote Repository: Uses a simulated URL structure for package fetching (not functional in real-world usage).

• package_manager.py: The core script of the package manager handling package operations.
• advanced_project/main.py: Main application file demonstrating the package manager usage.
• advanced_project/config.json: Configuration file for the application.
• advanced_project/utils.py: Utility functions for the application.
• advanced_project/tests/: Directory containing unit tests for the application.
• advanced_project/requirements.txt: Lists packages to be installed by the package manager.
• advanced_project/package_db.json: JSON file acting as a local database for installed packages.

To set up the package manager:

1. Clone or download the project repository.
2. Navigate to the advanced_project directory.
3. Ensure Python is installed on your system.

• Installing a Package: python package_manager.py install <package_name>
• Uninstalling a Package: python package_manager.py uninstall <package_name>
• Listing Installed Packages: python package_manager.py list

To run the sample application:

1. Navigate to the advanced_project directory.
2. Run python main.py.

Unit tests can be run by navigating to the tests directory and executing the test files.
