What are the differences between venv and virtualenv in Python?

Both venv and virtualenv are tools for creating isolated Python environments, but there are some key differences. venv is included in the Python standard library starting from Python 3.3, while virtualenv is a third-party package that works with both Python 2 and 3.

Can you explain the advantages of using virtualenv over venv?

Sure! Virtualenv offers more features, such as the ability to create environments for different Python versions and better support for older Python versions. It also allows for more customization.

Is it possible to use both venv and virtualenv in the same project?

Yes, you can use both in the same project, but it's generally recommended to stick to one to avoid confusion. Choose the one that best fits your needs.

Which one should I use for a new project?

If you're using Python 3.3 or later, venv is usually sufficient and simpler to use. However, if you need features from virtualenv, like cross-version support, then go with virtualenv.
