#51 Issue Resolved
Changes:

1. Replaced the use of os.system for executing shell commands with the subprocess module, which provides more flexibility and better handling of command execution.
2. Utilized the requests library instead of the http.client module for making HTTP requests, as it offers a more straightforward and user-friendly interface.
3. Implemented error handling for HTTP requests and responses to provide better feedback in case of failures.
4. Improved code readability and adherence to PEP 8 style guidelines.

Great work @anupammaurya6767 !

Can you add another "description" argument to the parser object so that users can add custom description to the repo (line 37)? Make sure to include the default value for the description argument.

As you are adding external dependencies, please add an updated requirements.txt in your next commit. Make these changes asap to merge this PR.
