+
+### How the Uninstaller Works:
+
+1.  **Detecting Python version**: The script detects the installed Python version using `python3 --version` and extracts the version number. If no Python version is detected, the script exits with an error message.
+    
+2.  **Uninstalling Python**: The script uninstalls the detected Python version along with related packages (`venv`, `dev`, `distutils`).
+    
+3.  **Uninstalling pip**: The script removes `pip`.
+    
+4.  **Removing the `deadsnakes` PPA**: It checks if the `deadsnakes` PPA exists in the system and removes it.
+    
+5.  **Cleaning up remaining packages**: It runs `apt autoremove` to remove unnecessary dependencies.
+    
+6.  **Verifying uninstallation**: It checks whether Python and `pip` are successfully uninstalled.
+    
+
+### How to Use the Uninstaller Script
+
+1.  **Create the script file**: Save the script as `uninstall_python.sh`.
+       
+    `nano uninstall_python.sh` 
+    
+2.  **Make the script executable**: Make the script executable using the `chmod` command:
+    
+    `chmod +x uninstall_python.sh` 
+    
+3.  **Run the script**: Execute the script:
+    
+    `./uninstall_python.sh`
