[Python-modules-team] Bug#878418: flake8: cannot check python2 code

[Sandro Tosi]

Package: flake8
Version: 3.2.1-1
Severity: important

Dear Maintainer,

flake8 switched to be a python3 package, so now the `flake8` program runs under
py3k, that means it cannot check python2 code anymore: f.e. if you run it
against a python2 script containing a `print` statement, flake8 generates a
`E999 SyntaxError: invalid syntax` error.

there is no equivalent flake8-py2 tool, so perfectly valid python2 code cannot
be checked with flake8 unless you explicitly call `python /usr/bin/flake8
/path/to/python2/code.py` which is not user friendly
