Yes, definitely. But other tools can be used in addition to solve their own problems.

Need to have multiple versions of python installed and easily accessible? Use pyenv.

Need to run tests across multiple versions of python? Use tox.

Need to freeze environments for deployment purposes? Use pip-tools.

Need to freeze the entire operating system? Use docker or vagrant.

Don't use tools you don't need. That would be silly.
