Switching virtual environments using ‘workon’ for managing Python virtual environments.

In Python, you can use either the virtualenv or venv module to create and manage virtual environments. These environments help us manage multiple projects on one computer, each with its own separate dependencies and Python version.

After creating a virtual environment using virtualenv or venv, we can use the workon command to switch between virtual environments. The workon command is provided by the virtualenvwrapper library, which needs to be installed beforehand.

Here are the steps for switching virtual environments using workon:

1. Install the virtualenvwrapper library.
2. Install virtualenvwrapper using pip.
3. Set up a virtual environment.
4. Create a virtual environment using virtualenvwrapper: mkvirtualenv
5. Create a virtual environment using venv: python -m venv
6. Switch virtual environment.
7. activate the virtual environment called <虚拟环境名称>
8. Exit the virtual environment.
9. turn off

Before using the workon command to switch virtual environments, you need to create and enter the virtual environment first. The workon command can only switch to virtual environments that have already been created.
