我在 C# 应用程序中托管 IronPython，并将主机的 API 注入全局范围。

我刚刚开始喜欢syntastic用 vimpylint来检查我的脚本。但是我[E0602, method_name] Undefined variable 'variable_name'对注入变量的所有错误消息感到恼火。

我知道使用# pylint: disable=E0602来禁用此错误消息，但我不希望仅针对某些特定变量名削弱真正有用的功能。

你如何处理这个问题？

目前，我在脚本的顶部执行此操作：

try:
    host_object = getattr(__builtins__, 'host_object')
except AttributeError:
    pass # oops, run this script inside the host application!!

我真正想做的是：

# pylint: declare=host_object, other_stuff

您可以将变量添加到 'additional-builtins' 选项，以便 pylint 将它们视为已定义。

这必须在 rc 文件中完成，不能在代码中内联完成。

在代码中禁用 E0602：

# make pylint think that it knows about 'injected_var' variable
injected_var = injected_var  # pylint:disable=invalid-name,used-before-assignment

显然，这需要每个模块执行一次，injected_var此行之后的所有出现对于 pylint 都是合法的。

实际上，有一种方法可以通过在dummy-variables-rgx（或旧版本 中的dummy -variables ）中指定特定的未定义变量来禁用 pylint 争论。默认包含并在执行时被用户指定的值覆盖：pylintdummy-variables_,dummypylint

$ pylint --dummy-variables-rgx='(_+[a-zA-Z0-9]*?$)|dummy|host_object'

或对于旧pylint版本：

$ pylint --dummy-variables='_,dummy,host_object'

或者如果是VSCodepylint的配置（可以通过按+打开）：User/Workspace SettingsCtrl,

"python.linting.pylintArgs": [
    "--dummy-variables-rgx='(_+[a-zA-Z0-9]*?$)|dummy|qdict'"
]

有good-names=host_object,other_stuff或additional-builtins=...为此，或者对于一些高级的东西，你可以通过修改正则表达式variable-rgx。

不适用于变量，但您可以为具有 var 的行禁用它。参见参考文献。

我刚遇到这个问题，我只是在 pylintrc 文件中添加了禁用选项。就我而言，我正在编写一个小脚本，并且一些 pylint 检查有点矫枉过正。所以我禁用了未定义的变量错误

E: 32,40: Undefined variable 'description' (undefined-variable)

经过

禁用=E0602，E0603

把它贴在行尾，你就完成了：

并dummy-variables-rgx没有为我做伎俩。我遇到了仅在集群上可用的包问题，而不是在本地开发时。我不得不使用“附加内置”设置，并将其添加到我的 .pylintrc 中。

additional-builtins: mssparkutils
