What does '# noqa' mean in Python comments?
提问by Ishpreet
While searching through a Python project, I found a few lines commented with # noqa.
在搜索 Python 项目时，我发现有几行用# noqa.
import sys
sys.path.append(r'C:\dev')
import some_module # noqa
What does noqamean in Python? Is it specific to Python only?
noqa在 Python中是什么意思？它仅特定于 Python 吗？

Adding # noqato a line indicates that the linter (a program that automatically checks code quality) should not check this line. Any warnings that code may have generated will be ignored.
添加# noqa到一行表示 linter（自动检查代码质量的程序）不应检查该行。代码可能生成的任何警告都将被忽略。
That line may have something that "looks bad" to the linter, but the developer understands and intends it to be there for some reason.
这条线可能有一些对 linter 来说“看起来很糟糕”的东西，但开发人员理解并打算出于某种原因将它放在那里。

noqa = NO-QA (NO Quality Assurance)
noqa = NO-QA（无质量保证）
It's generally referred in Python Programming to ignore the PEP8warnings.
通常在 Python Programming 中提到忽略PEP8警告。
In simple words, lines having #noqa at the end will be ignored by the linter programs and they won't raise any warnings.
简而言之，以 #noqa 结尾的行将被 linter 程序忽略，并且不会引发任何警告。

You know what? Even Guido van Rossum (the creator of Python) asked this question before:D
你知道吗？甚至 Guido van Rossum（Python 的创造者）之前也问过这个问题：D
It used to be "nopep8" but when Flake8 and Pep8 wanted a common qualifier @florentx suggested "NoQA" as in "No Quality Assurance" (iirc) and it stuck.
它曾经是“nopep8”，但是当 Flake8 和 Pep8 想要一个共同的限定符时，@florentx 建议使用“NoQA”作为“No Quality Assurance”（iirc）并且它卡住了。
Some basic usagesof # noqa(with flake8):
# flake8: noqa: filesthat contain this lineare skipped- linesthat contain a
# noqacomment at the end: will not issue warnings # noqa: <error>, e.g.,# noqa: E234at the end: ignore specific errorson a line- multiple error codes can be given, separated by comma
- the colon before the list of codes is required
# flake8: noqa:跳过包含这一行的文件- 最后包含
# noqa注释的行：不会发出警告 # noqa: <error>，例如，# noqa: E234最后：忽略一行中的 特定错误- 可以给出多个错误代码，以逗号分隔
- 代码列表前的冒号是必需的
