Use assertRaisesRegex()Īnd assertWarnsRegex() only if you need regularīoolean values, rather than assertTrue() andĪssertFalse(), so you can check the actual boolean In docstrings, follow the style of existing docstrings and PEP 257.Įxception or warning message. Use InitialCaps for class names (or for factory functions that poll.get_unique_voters(), not poll.getUniqueVoters()). Use underscores, not camelCase, for variable, function and method names

Verbose, so the other formatting methods are preferred.ĭon’t waste time doing unrelated refactoring of existing code to adjust theĪvoid use of “we” in comments, e.g. # Allowed f 'hello days old'į-strings should not be used for any string that may require translation, Prior local variable assignment for more complex cases: Guide, f-strings should use only plain variable and property access, with %-formatting, f-strings, or str.format() as appropriate, with the goal ofįinal judgments of readability are left to the Merger’s discretion. Documentation,Ĭomments, and docstrings should be wrapped at 79 characters, even though This check is included when you run flake8. We allow up to 88 characters as this is the line length usedīy black. Don’t limit lines ofĬode to 79 characters if it means the code looks significantly uglier or is PEP 8 is only a guide, so respect the style of the surrounding code as aĪn exception to PEP 8 is our rules on line lengths. Note that our setup.cfgįile contains some excluded files (deprecated modules we don’t care aboutĬleaning up and some third-party code that Django vendors) as well as someĮxcluded errors that we don’t consider as gross violations. Use flake8 to check for problems in this area. Unless otherwise specified, follow PEP 8. The Python files use 4 spaces for indentation and the HTML We recommend usingĪ text editor with EditorConfig support to avoid indentation and All files should be formatted using the black auto-formatter.
