🛠️ Solution: Installing Python 2

To resolve this issue, follow these simple steps:

Step 1: Install Python 2 on your system. You can download it from the official Python website (python.org). Make sure to choose the Python 2.x version and not Python 3.

Step 2: After Python 2 is installed, you need to set up the Python path in your system environment variables. Here's how to do it:

• On Windows:

  1. Right-click on "My Computer" (or "This PC") and select "Properties."

  2. In the system properties window, click on the "Advanced system settings" link.

  3. In the "System Properties" window, click on the "Environment Variables" button.

  4. In the "Environment Variables" window, find the "Path" variable under "System variables" and click on "Edit."

  5. Add the path to your Python installation directory (e.g., "C:\Python27") at the end of the "Variable value" field.

  6. Click "OK" to save the changes.

Step 3: Now, open a new terminal or command prompt window and run the following command to ensure Python is correctly installed and recognized:

python --version

If you see the Python version printed, it means Python has been successfully installed and recognized.
