如果运行pylint --generate-rcfile > pylintrc并查看默认的rc文件，则会看到以下禁用的警告列表。

为什么默认情况下禁用它们？

Answer 1

我认为这种默认的rc文件旨在将pylint应用于python2代码，而不会产生大量错误和警告。注意：大多数禁用的语句都属于python2语法和标准库api：

print-statement-print是Python2中的一条语句，在Python3中是一个函数
old-raise-syntax-有except Exception, e语法对Python3无效，在Python3中except Exception as e仅有效
xrange-builtin-xrange替换为range
等

因此，使用此默认rc，您可以对python2代码使用pylint来查找诸如redefined-outer-name，line-too-long之类的其他错误内容，而不会为有效的Python2语法和标准库带来烦人的错误和警告电话。

为什么默认情况下禁用一堆消息？

pylint确实默认禁用了某些消息，原因可能是   他们容易产生误报，或者他们自以为是   不包含在默认消息中。但是大多数残疾人   消息来自Python 3移植检查器，该检查器已被禁用   默认。需要使用--py3k标志进行特殊激活。

为什么默认的pylintrc会有这么多禁用的消息？
