#noqa works only on one line import but not on import ()

Question

I have a list of imports I used in a file:

import (
a,
b,
c 
)

However, this imports are @pytest.fixture and thus, they are not called explicitly in the code and so I got "imported but unused" Flake8 error, as expected.

I tried to do the following:

1. use as, e.g.:

   import (
       a as a,
       b as b,
       ...
   )
   

2. add #noqa at each line end, e.g.:

   import (
       a, #noqa
       b, #noqa
       ...
   )
   

3. add #noqa at the end of the import, i.e.:

   import (
       ...
   ) #noqa
   

But none have worked. Only splitting the import into separate lines did the trick, i.e.

import a #noqa
import b #noqa
...

Why is that and am I missing a simpler way to do so?

Answer 1

your original code is a syntax error so I'm assuming you mean something like this:

from mod import (
    a,
    b,
    c,
)

if you run this through flake8 you get:

$ flake8 t.py 
t.py:1:1: F401 'mod.a' imported but unused
t.py:1:1: F401 'mod.b' imported but unused
t.py:1:1: F401 'mod.c' imported but unused

to inline-disable lint codes, use a # noqa comment on the line where the error occurs (or if it is a triple quoted string or backslash-escaped string then use the last line) -- the former case applies here

from mod import (  # noqa: F401
    a,
    b,
    c,
)

and:

$ flake8 t.py
$ echo $?
0
