Switch Python Version for Vim & Syntastic

Question

Is it possible to change the python version used by syntastic for syntax checking?

As the Issue https://github.com/scrooloose/syntastic/issues/385 indicates I could

Answer 1

I managed to convince Syntastic to handle Python 3 syntax with

pip3 install --user flake8

(to make python3 -m flake8 *.py work) and then, in vim:

let g:syntastic_python_flake8_exec = 'python3'
let g:syntastic_python_flake8_args = ['-m', 'flake8']
