We will use Homebrew to install Python 3.8 and will then move on to creating a virtual environment. So to set up a virtual environment, we won't be using virtualenv or virtualenvwrapper module, which are most popular to set up a virtual environment.Д«ut we will be using the venv module which comes as a default with Python 3.x version and is recommended to use for virtual environment creation. You can set up a different virtual environment for each project for example if you are working on one project based on Tkinter module, some other projects based on Numpy module, then you can easily do this. We can have different versions of Python installed inside the virtual environment. When we have a virtual environment, then we can install new packages inside the virtual environment which will not affect the operating system's python modules.
