1. Open the terminal by pressing `Ctrl+Alt+T` on the keyboard.

2. Type the following command to check if Python 3.8 is already installed:

   python3.8 --version

If Python 3.8 is installed, you will see its version number. If not, you can install it using the following command:

This command will create a virtual environment named `myenv` in the current directory.

4. Activate the virtual environment using the following command:

   source myenv/bin/activate

This will activate the virtual environment, and you will see `(myenv)` at the beginning of the terminal prompt.

5. Now you can install any Python packages you need for your project using `pip`, the Python package manager.

   deactivate

This will return you to the system's default Python environment.
