    python -m venv myenv
    

    Replace myenv with the name you want to give your virtual environment.

  4. Activate the virtual environment by running the following command:
    source myenv/bin/activate
    

    If you’re using Windows, run the following command instead:

    myenv\Scripts\activate.bat
    
  5. You should now see the name of your virtual environment in your terminal prompt. You can now install packages and dependencies in this environment without affecting your system’s Python environment.
    pip install package-name
    

    Replace package-name with the name of the package you want to install.

When you’re done working in your virtual environment, you can deactivate it by running the following command:

deactivate

Creating a virtual environment is a great way to update Python and install packages without affecting your system’s Python environment. It’s also a good practice to use virtual environments when working on different projects that require different dependencies.
