How To Write A Pep8 Configuration (pep8.rc) File?

I found the documentation for pep8 but wasn't able to understand how to write these. I couldn't even find any examples with options other than setting max-line-length and ignore. I

Solution 1:

The preferred way is to use a setup.cfg in the top-level of the project (.cfg has the same syntax as a .ini file), which should contain a [pep8] section. For example:

[pep8]ignore = E226,E302,E41
max-line-length = 160

Note: the error codes are defined in the pep8 docs.

• autopep8 find this same [pep8] section as pep8.
• flake8 needs a [flake8] section in setup.cfg.
• yapf looks for a [yapf] section in setup.cfg.

Solution 2:

Sadly, the answer from Andy Hayden does not work for pytest / pytest-pep8 / flake8.

pytest-pep8

For that, you have to use either

# content of setup.cfg[pytest]pep8maxlinelength = 99

or

[pytest]max-line-length=99

Strangely, the following does not work

[tool:pytest]max-line-length=99

pytest-flake8

Add

[flake8]max-line-length=99

Solution 3:

They renamed pep8 to pycodestyle to avoid confusion.

You can create a setup.cfg file with:

[pycodestyle]
ignore = E226,E302,E41
max-line-length = 119
exclude =
    tests/
    docs/

For the error codes, you can read this documentation.
