Hi there!

The “permission denied” error generally signifies that your current user does not have sufficient permissions to execute the Python script.

Consider trying these steps:

1. **Check the file permissions.**
In Unix systems, you can view file permissions using the command `ls -l YourScript.py`. It will return something resembling `-rwxrwxrwx`, which indicates user, group, and others’ respective permissions. If the ‘x’ (execute) permission is missing for the user, then it’s the root cause of the issue.

2. **Change the permissions.**
You can change your file permissions to let your user execute it using the command `chmod u+x YourScript.py`. This permits your user to execute the script.

3. **Check the Shebang line.**
The first line of your python script should be something like `#!/usr/bin/env python3` to tell the system that this is a Python script. Ensure Python is properly installed and functioning as expected by testing it in your terminal.

4. **Ensure the File is Not Open Somewhere Else.**
If the file is being used by another application, you may not have permission to execute. Make sure that it’s closed in all other programs.

5. **Run as a Different User.**
If nothing else works, use `sudo python3 YourScript.py` to execute your script as the root user. However, be cautious with this because running as the root user can inadvertently cause a lot of damage.

Remember if you are on a Windows system the process might be a bit different. Let me know if you are and I can provide further help!

Best of luck and Happy Coding!
