What are the differences between Python 3.10 virtual environments and virtualenv?

What are the differences between Python 3.10 virtual environments and virtualenv?

Python 3.10 includes the built-in venv module for creating virtual environments, while virtualenv is a third-party tool. venv is simpler and comes with Python, but virtualenv offers more features and compatibility with older Python versions.

Can I 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 with one to avoid confusion.

Which one should I choose for a new project?

If you're using Python 3.10 or later, venv is usually sufficient. However, if you need features like support for multiple Python versions, virtualenv might be a better choice.

Are there any performance differences between them?

In most cases, the performance difference is negligible. However, virtualenv can be slightly slower to create environments due to its additional features.
