PEP8: continuation line over-indented for visual indent
提问by Sc4r
I have this line of code which goes over the line and when testing for pep8 errors I get: line too long. So to try and fix this I used slash('\') but then I get continuation line over-indented for visual indent. What can I do to fix this?
我有这行代码，当测试pep8错误时，我得到：行太长了。因此，为了尝试解决此问题，我使用了斜杠（'\'），但随后我将连续行过度缩进以进行视觉缩进。我能做些什么来解决这个问题？
Things I've tried:
我尝试过的事情：
if first_index < 0 or second_index > \
self._number_of_plates - 1:
raise ValueError
continuation line over-indented for visual indent
if first_index < 0 \
or second_index > \
self._number_of_plates - 1:
raise ValueError
continuation line over-indented for visual indent
if first_index < 0 or \
second_index > self._number_of_plates - 1:
raise ValueError
continuation line over-indented for visual indent
if first_index \
< 0 or second_index \
> self._number_of_plates - 1:
raise ValueError
continuation line over-indented for visual indent

The line-extending backslash has the issue of having trailing whitespace that can break your code. This is a popular fix and is PEP8-compliant:
行扩展反斜杠的问题是尾随空格可能会破坏您的代码。这是一个流行的修复程序并且符合 PEP8：
if (first_index < 0 or
second_index > self._number_of_plates - 1):
