Here completed the issue #93

[Karmvirjadeja]

1. Readability
   In the optimized script, clear echo statements and comments are added to explain each major step (e.g., creating a virtual environment, cloning a repository, downloading files, etc.).
   This makes it much easier for future developers (or even yourself) to understand the script, debug it, and modify it when needed.

2. Error Handling
   In the optimized script, I've added error handling using || operators, which immediately exit the script with a helpful error message if a command fails.
   For example, if git clone fails, the script will exit immediately with the message Failed to clone repository. Similarly, for wget or tar failures, an error message will be shown, and the script will stop.
   This helps prevent partial setups and provides immediate feedback, so you can fix issues early.

3. Efficiency
   In the optimized script, I removed the redundant mkdir command, letting tar handle the creation of the directory if necessary. This simplifies the script and improves its performance, as it avoids running an extra command when it's not needed.
   By doing this, the script becomes more efficient and cleaner, reducing unnecessary steps.

4. Proper Deactivation of Virtual Environment
   The optimized script uses the correct deactivate command, ensuring that the virtual environment is properly deactivated after the setup process is complete.
   This ensures that the environment is clean and avoids potential issues in subsequent steps or scripts.
