flake8-broken-line

wemake.services Build Status codecov Python Version PyPI version wemake-python-styleguide

Do not break the line! 🚨

Installation

pip install flake8-broken-line

It is also a valuable part of wemake-python-styleguide.

Code example

Things we check with this plugin:

# String line breaks, use `()` or `"""` instead:

some_string = 'first line\
second line'

# Use a single line, `()`, or new variables instead:

if 1 == 1 and \
    2 == 2:
    print('Do not do that!')

# Do not use for method chaining:
some_object \
  .call_method(param1, param2) \
  .call_other(keyword=value) \
  .finalize()

# Instead use:
some_objects.call_method(
    param1, param2,
).call_other(
    keyword=value
).finalize()
