Python code requires a running environment to run. It is not recommended to use the system interpreter global interpreter directly in Pycharm. The third-party packages to be used are also managed here.
When creating a Python project, pycharm can choose the virtual environment you need to use. This time we introduce the use of the default Virtualenv.
The virtual running environment can separate projects. Each project can have an independent running environment. Of course, you can let multiple projects share a virtual environment.

Fill in the project path and project name in Location;
The second Location is the path of the virtual environment
Select the global Python interpreter in the Base interpreter drop-down box;
Check Inherit global site-packages: you can use third-party libraries in the base interpreter (that is, use cmd command to install the third-party library globally), if not selected, it will be completely isolated from the outside world;
Check Make available to all projects: This virtual environment can be provided to other projects.
Virtualenv creates a venv folder in the root directory of the project by default to store the contents of the virtual environment.
