If you're feeling confident, use `--fast`. -_Black_ will enforce single empty lines between a class-level docstring and the first -following field or method. This conforms to -[PEP 257](https://www.python.org/dev/peps/pep-0257/#multi-line-docstrings). - -_Black_ won't insert empty lines after function docstrings unless that empty line is -required due to an inner function starting immediately after. - -### Trailing commas - -_Black_ will add trailing commas to expressions that are split by comma where each -element is on its own line. This includes function signatures. - -Unnecessary trailing commas are removed if an expression fits in one line. This makes it -1% more likely that your line won't exceed the allotted line length limit. Moreover, in -this scenario, if you added another argument to your call, you'd probably fit it in the -same line anyway. That doesn't make diffs any larger. - -One exception to removing trailing commas is tuple expressions with just one element. In -this case _Black_ won't touch the single trailing comma as this would unexpectedly -change the underlying data type. Note that this is also the case when commas are used -while indexing. This is a tuple in disguise: `numpy_array[3, ]`. - -One exception to adding trailing commas is function signatures containing `*`, `*args`, -or `**kwargs`. In this case a trailing comma is only safe to use on Python 3.6. _Black_ -will detect if your file is already 3.6+ only and use trailing commas in this situation. -If you wonder how it knows, it looks for f-strings and existing use of trailing commas -in function signatures that have stars in them. In other words, if you'd like a trailing -comma in this situation and _Black_ didn't recognize it was safe to do so, put it there -manually and _Black_ will keep it. - -### Strings - -_Black_ prefers double quotes (`"` and `"""`) over single quotes (`'` and `'''`). It -will replace the latter with the former as long as it does not result in more backslash -escapes than before. - -_Black_ also standardizes string prefixes, making them always lowercase. On top of that, -if your code is already Python 3.6+ only or it's using the `unicode_literals` future -import, _Black_ will remove `u` from the string prefix as it is meaningless in those -scenarios. - -The main reason to standardize on a single form of quotes is aesthetics. Having one kind -of quotes everywhere reduces reader distraction. It will also enable a future version of -_Black_ to merge consecutive string literals that ended up on the same line (see -[#26](https://github.com/psf/black/issues/26) for details). - -Why settle on double quotes? They anticipate apostrophes in English text. They match the -docstring standard described in -[PEP 257](https://www.python.org/dev/peps/pep-0257/#what-is-a-docstring). An empty -string in double quotes (`""`) is impossible to confuse with a one double-quote -regardless of fonts and syntax highlighting used. On top of this, double quotes for -strings are consistent with C which Python interacts a lot with. - -On certain keyboard layouts like US English, typing single quotes is a bit easier than -double quotes. The latter requires use of the Shift key. My recommendation here is to -keep using whatever is faster to type and let _Black_ handle the transformation. - -If you are adopting _Black_ in a large project with pre-existing string conventions -(like the popular -["single quotes for data, double quotes for human-readable strings"](https://stackoverflow.com/a/56190)), -you can pass `--skip-string-normalization` on the command line. This is meant as an -adoption helper, avoid using this for new projects. - -### Numeric literals - -_Black_ standardizes most numeric literals to use lowercase letters for the syntactic -parts and uppercase letters for the digits themselves: `0xAB` instead of `0XAB` and -`1e10` instead of `1E10`. Python 2 long literals are styled as `2L` instead of `2l` to -avoid confusion between `l` and `1`. - -### Line breaks & binary operators - -_Black_ will break a line before a binary operator when splitting a block of code over -multiple lines. This is so that _Black_ is compliant with the recent changes in the -[PEP 8](https://www.python.org/dev/peps/pep-0008/#should-a-line-break-before-or-after-a-binary-operator) -style guide, which emphasizes that this approach improves readability. - -This behaviour may raise `W503 line break before binary operator` warnings in style -guide enforcement tools like Flake8. Since `W503` is not PEP 8 compliant, you should -tell Flake8 to ignore these warnings. - -### Slices - -PEP 8 -[recommends](https://www.python.org/dev/peps/pep-0008/#whitespace-in-expressions-and-statements) -to treat `:` in slices as a binary operator with the lowest priority, and to leave an -equal amount of space on either side, except if a parameter is omitted (e.g. -`ham[1 + 1 :]`). It also states that for extended slices, both `:` operators have to -have the same amount of spacing, except if a parameter is omitted (`ham[1 + 1 ::]`). -_Black_ enforces these rules consistently. - -This behaviour may raise `E203 whitespace before ':'` warnings in style guide -enforcement tools like Flake8. Since `E203` is not PEP 8 compliant, you should tell -Flake8 to ignore these warnings. - -### Parentheses - -Some parentheses are optional in the Python grammar. Any expression can be wrapped in a -pair of parentheses to form an atom. There are a few interesting cases: - -- `if (...):` -- `while (...):` -- `for (...) in (...):` -- `assert (...), (...)` -- `from X import (...)` -- assignments like: - - `target = (...)` - - `target: type = (...)` - - `some, *un, packing = (...)` - - `augmented += (...)` - -In those cases, parentheses are removed when the entire statement fits in one line, or -if the inner expression doesn't have any delimiters to further split on. If there is -only a single delimiter and the expression starts or ends with a bracket, the -parenthesis can also be successfully omitted since the existing bracket pair will -organize the expression neatly anyway. Otherwise, the parentheses are added. - -Please note that _Black_ does not add or remove any additional nested parentheses that -you might want to have for clarity or further code organization. For example those -parentheses are not going to be removed: - -```py3 -return not (this or that) -decision = (maybe.this() and values > 0) or (maybe.that() and values < 0) -``` +## The _Black_ code style -### Call chains - -Some popular APIs, like ORMs, use call chaining. This API style is known as a -[fluent interface](https://en.wikipedia.org/wiki/Fluent_interface). _Black_ formats -those by treating dots that follow a call or an indexing operation like a very low -priority delimiter. It's easier to show the behavior than to explain it. Look at the -example: - -```py3 -def example(session): - result = ( - session.query(models.Customer.id) - .filter( - models.Customer.account_id == account_id, - models.Customer.email == email_address, - ) - .order_by(models.Customer.id.asc()) - .all() - ) -``` +_Black_ is a PEP 8 compliant opinionated formatter. _Black_ reformats entire files in +place. It is not configurable. It doesn't take previous formatting into account. Your +main option of configuring _Black_ is that it doesn't reformat blocks that start with +`# fmt: off` and end with `# fmt: on`, or lines that ends with `# fmt: skip`. Pay +attention that `# fmt: on/off` have to be on the same level of indentation. To learn +more about _Black_'s opinions, to go +[the_black_code_style](https://github.com/psf/black/blob/master/docs/the_black_code_style.md). -### Typing stub files - -PEP 484 describes the syntax for type hints in Python. One of the use cases for typing -is providing type annotations for modules which cannot contain them directly (they might -be written in C, or they might be third-party, or their implementation may be overly -dynamic, and so on). - -To solve this, -[stub files with the `.pyi` file extension](https://www.python.org/dev/peps/pep-0484/#stub-files) -can be used to describe typing information for an external module. Those stub files omit -the implementation of classes and functions they describe, instead they only contain the -structure of the file (listing globals, functions, and classes with their members). The -recommended code style for those files is more terse than PEP 8: - -- prefer `...` on the same line as the class/function signature; -- avoid vertical whitespace between consecutive module-level functions, names, or - methods and fields within a single class; -- use a single blank line between top-level class definitions, or none if the classes - are very small. - -_Black_ enforces the above rules. There are additional guidelines for formatting `.pyi` -file that are not enforced yet but might be in a future version of the formatter: - -- all function bodies should be empty (contain `...` instead of the body); -- do not use docstrings; -- prefer `...` over `pass`; -- for arguments with a default, use `...` instead of the actual default; -- avoid using string literals in type annotations, stub files support forward references - natively (like Python 3.7 code with `from __future__ import annotations`); -- use variable annotations instead of type comments, even for stubs that target older - versions of Python; -- for arguments that default to `None`, use `Optional[]` explicitly; -- use `float` instead of `Union[int, float]`. +Please refer to this document before submitting an issue. What seems like a bug might be +intended behaviour. ## Pragmatism Early versions of _Black_ used to be absolutist in some respects. They took after its initial author.
