If you install packages to your operating system’s global Python, these packages will mix with the system-relevant packages. Linux and macOS come preinstalled with a version of Python that the operating system uses for internal tasks. In this section, you’ll learn more about them, as well as other problems that virtual environments mitigate. Several issues can come up if all of your external packages land in the same folder. If you want to, however, you can keep in mind that when someone mentions Python’s site-packages directory, they could be talking about two different directories.

In fact, you probably won’t ever need to think about it again. To work with virtual environments, you don’t need to worry about the implementation detail of a single site-packages folder or two separate ones. If two different paths show up, then your operating system makes this distinction.Įven if your operating system distinguishes between the two, dependency conflicts will still arise because all purelib modules will go into a single location for purelib modules, and the same will happen with the platlib modules. If both outputs are the same, then your operating system doesn’t put purelib modules into a different folder than platlib modules. Most likely, both outputs will show you the same path. get_path ( "platlib" ) '/Users/name/path/to/venv/lib/python3.10/site-packages' get_path ( "purelib" ) '/Users/name/path/to/venv/lib/python3.10/site-packages' > sysconfig. Gaining a better understanding of how they work, why you need them, and what you can do with them will help you master your Python programming workflow. Virtual environments are a common and effective technique used in Python development.

Choose additional tools for managing your Python versions and virtual environments.

Deactivate and remove virtual environments.

Customize your virtual environments using optional arguments to venv.

Visualize what Python does when you create a virtual environment.

Explain why you want to isolate external dependencies.

Create and activate a Python virtual environment.

After you’ve learned to work with virtual environments, you’ll know how to help other programmers reproduce your development setup, and you’ll make sure that your projects never cause dependency conflicts for one another.īy the end of this tutorial, you’ll know how to: Each environment can use different versions of package dependencies and Python. In this tutorial, you’ll learn how to work with Python’s venv module to create and manage separate virtual environments for your Python projects.
