How to write a pep8 configuration (pep8.rc) file?

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

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.
