How to disable a pep8 error in a specific file?

Question

I tried with

#:PEP8 -E223

or

# pep8: disable=E223

I thought the second would work but doesn't seems to work.

Do you have an idea how I can handle this ?

As far as I know, you can't. You can disable errors or warnings user wide, or per project. See the documentation.

Instead, you can use the # noqa comment at the end of a line, to skip that particular line (see patch 136). Of course, that would skip all PEP8 errors.

The main author argues against source file noise, so they suggested # pep8 comments don't get included.

Note that there is also nopep8, which is the equivalent. noqa (which stands for No Quality Assurance was added in version 1.4.1 to support people running pyflakes next to pep8.

Thanks. But in my case, I don't want to skip a specific line :-( To my mind, it is less poluting to add something like "# pep8: disable E221" at the begining of the file than specify each line to ignore. But it is my point ! Thanks for the answer. – Flows Aug 27 '13 at 07:24

Try putting # nopep8 at the end of the line (after two spaces). So if the line of code is:

h=1+2+3+4+5+6+func( "hello","world")

then to ignore the copious pep8 errors for that line it becomes:

h=1+2+3+4+5+6+func( "hello","world")  # nopep8

It seems that this can be combined with a specific error type, e.g. `# nopep8: E501` – Bilal Akil May 17 '22 at 07:07

the irony of making a line longer to say you want it ignored for length – Blundell Sep 09 '22 at 10:52

Let me add something that was probably introduced after all the previous answers were posted.

If you use Flake8, you can ignore a specific violation raised in a specific line, by adding

# noqa: F401

at the end of the line, where F401 here is an example of an error code. For a list of all violations code, see http://flake8.pycqa.org/en/3.5.0/user/error-codes.html and https://pycodestyle.readthedocs.io/en/latest/intro.html#error-codes

You can also ignore all violations in an entire file by adding

# flake8: noqa

anywhere in the file.

Reference: http://flake8.pycqa.org/en/3.5.0/user/violations.html

Thank you sir, this does not answer the precise question but it does come up in a search for what you answered and that is helpful :) Disabling at a line is what I and others who will arrive here needed! — rjurney, Aug 25 '22 at 18:15

You can use --ignore flag to disable the error you mentioned above

pep8 --ignore=E223 file_name.py

for multiple errors

pep8 --ignore=E223,E501 file_name.py

For more in depth knowledge of other flags you can scan through http://pep8.readthedocs.org/en/latest/intro.html

You can do that using Flake8 together with https://github.com/jayvdb/flake8-putty

`flake8-putty` is definitely the best approach overall - cause it allows a much more granular control which things to disable for what files. – alecxe Jun 22 '17 at 16:34

If you use Flake8 3.7.0+, you can ignore specific warnings for entire files using the --per-file-ignores option.

Command-line usage:

flake8 --per-file-ignores='project/__init__.py:F401,F403 setup.py:E121'

This can also be specified in a config file:

[flake8]
per-file-ignores =
    __init__.py: F401,F403
    setup.py: E121
    other/*: W9

You can do that with, for example, your setup configuration file (setup.cfg):

[tool:pytest]
pep8ignore =
    *.py E501 W503
    api.py E402                <=============== HERE
    doc/* ALL
pep8maxlinelength = 120
flakes-ignore =
    UnusedImport
filterwarnings =
  ignore::DeprecationWarning

In the IDE of LiClipse, you can add --ignore=E501 in Code Analysis from Preference.

If anyone uses Eclipse like IDE, this is the convenient way to do it.
