'noqa: C901' does not work as documented about mccabe HOT 3 CLOSED

A few things:

1. McCabe doesn't implement # noqa - Flake8 does
2. # noqa in Flake8 belongs on the line that's being reported. So in your example, the line number is 2 which corresponds with def complex_function(): so instead this should look like

def complex_function():  # noqa: C901
    ...

3. Issue trackers are not for Q&A, they're for bug reports. Use stackoverflow for questions.

Note for future visitors --

Moving the noqa line does fix the problem for:

$ flake8 --max-complexity 3 cyclo.py
cyclo.py:2:1: C901 'complex_function' is too complex (4)

However, it does not fix the problem for:

$ python3 -m mccabe --min 3 cyclo.py
1:0: 'complex_function' 4

This is because (as far as I can tell) mccabe does not provide any way to silence warnings, and you must use flake8 with mccabe as a plugin if you want that functionality.

That's correct @raxod502
