User-made splits are respected when they do not exceed the line l limit. Line continuation backslashes are converted into parenthesized strings. Unnecessary parentheses are stripped. The stability and status of this feature is tracked in [this issue](https://github.com/psf/black/issues/2188). + +### Improved line breaks + +For assignment expressions, _Black_ now prefers to split and wrap the right side of the +assignment instead of left side. For example: + +```python +some_dict[ + "with_a_long_key" +] = some_looooooooong_module.some_looooooooooooooong_function_name( + first_argument, second_argument, third_argument +) +``` + +will be changed to: + +```python +some_dict["with_a_long_key"] = ( + some_looooooooong_module.some_looooooooooooooong_function_name( + first_argument, second_argument, third_argument + ) +) +``` + +### Improved parentheses management + +For dict literals with long values, they are now wrapped in parentheses.
