## isort
[isort](https://pypi.org/p/isort/) helps to sort and format imports in your Python code.
_Black_ also formats imports, but in a different way from isort's defaults which leads
to conflicting changes.
-### Configuration
+### Profile
+
+Since version 5.0.0, isort supports
+[profiles](https://pycqa.github.io/isort/docs/configuration/profiles/) to allow easy
+interoperability with common code styles. You can set the black profile in any of the
+[config files](https://pycqa.github.io/isort/docs/configuration/config_files/) supported
+by isort. Below, an example for `pyproject.toml`:
+
+```toml
+[tool.isort]
+profile = "black"
+```
+
+### Custom Configuration
+
+If you're using an isort version that is older than 5.0.0 or you have some custom
+configuration for _Black_, you can tweak your isort configuration to make it compatible
+with _Black_. Below, an example for `.isort.cfg`:
```
multi_line_output = 3
_Black_ wraps imports that surpass `line-length` by moving identifiers into their own
indented line. If that still doesn't fit the bill, it will put all of them in separate
lines and put a trailing comma. A more detailed explanation of this behaviour can be
-[found here](https://github.com/psf/black#how-black-wraps-lines).
+[found here](https://github.com/psf/black/blob/master/docs/the_black_code_style.md#how-black-wraps-lines).
isort's default mode of wrapping imports that extend past the `line_length` limit is
"Grid".
**Please note** `ensure_newline_before_comments = True` only works since isort >= 5 but
does not break older versions so you can keep it if you are running previous versions.
-If only isort >= 5 is used you can add `profile = black` instead of all the options
-since [profiles](https://timothycrosley.github.io/isort/docs/configuration/profiles/)
-are available and do the configuring for you.

### Why those options above?
-When breaking a line, _Black_ will break it before a binary operator. This is compliant
-with PEP 8, but this behaviour will cause flake8 to raise
-`W503 line break before binary operator` warnings.
-
In some cases, as determined by PEP 8, _Black_ will enforce an equal amount of
whitespace around slice operators. Due to this, Flake8 will raise
-`E203 whitespace before ':'` warnings.
+`E203 whitespace before ':'` warnings. Since this warning is not PEP 8 compliant, Flake8
+should be configured to ignore it via `extend-ignore = E203`.
-Since both of these warnings are not PEP 8 compliant, Flake8 should be configured to
-ignore these warnings via `extend-ignore = E203, W503`.
+When breaking a line, _Black_ will break it before a binary operator. This is compliant
+with PEP 8 as of
+[April 2016](https://github.com/python/peps/commit/c59c4376ad233a62ca4b3a6060c81368bd21e85b#diff-64ec08cc46db7540f18f2af46037f599).
+There's a disabled-by-default warning in Flake8 which goes against this PEP 8
+recommendation called `W503 line break before binary operator`. It should not be enabled
+in your configuration.
Also, as like with isort, flake8 should be configured to allow lines up to the length
limit of `88`, _Black_'s default. This explains `max-line-length = 88`.
```ini
[flake8]
max-line-length = 88
-extend-ignore = E203, W503
+extend-ignore = E203
```
</details>
```cfg
[flake8]
max-line-length = 88
-extend-ignore = E203, W503
+extend-ignore = E203
```
</details>
```ini
[flake8]
max-line-length = 88
