What are the differences between venv and virtualenv in Python?

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

Are there any advantages of using virtualenv over venv?

Yes, virtualenv supports older versions of Python and offers more features, such as the ability to create environments with different Python interpreters.

Can I use both tools together?

Yes, you can use virtualenv to create a virtual environment and then use venv within that environment, but it's generally not necessary.

Which one should I use for my new project?

If you're using Python 3.3 or later, venv is sufficient for most projects. If you need compatibility with Python 2 or additional features, consider using virtualenv.
