How to switch betwen Python 2 and 3 when using Flycheck with flake8 in Emacs?

By installing Flycheck for Emacs, I set the parsing to flake8.

Installing flake8with pip install flake8makes Flycheck a Python 2 syntax checker.

However, use pip3 install flake8makes Flycheck a syntax check for Python 3.

How can I switch between modes for Python 2 and 3 in Emacs 24?
