如何禁用文件中特定变量的pylint'未定义变量'错误？

Question

我在C＃应用程序中托管IronPython，并将主机的API注入全局范围。

我刚刚开始热爱syntastic vim与pylint检查我的脚本。但是我对注入变量的所有[E0602, method_name] Undefined variable 'variable_name'错误消息感到恼火。

我知道使用# pylint: disable=E0602来禁用此错误消息，但我不想为某些特定变量名称削弱一个非常有用的功能。

你如何处理这个问题？

目前，我在我的脚本的顶部这样做：

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

我真的想做到这一点：

# pylint: declare=host_object, other_stuff 

Answer 1

不变量，但你可以将其禁用对于具有var的线条。请参阅ref。

Answer 2

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

这必须在一个rc文件中完成，它不能在代码中内联。

Answer 3

有good-names=host_object,other_stuff或additional-builtins=...为此，或对于一些先进的东西，你可以通过variable-rgx修改正则表达式。

Answer 4

代码禁用E0602：

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

显然，一个需要每个模块进行一次的injected_var所有出现这条线后，也可以合法的pylint的。

Answer 5

我刚刚遇到了这个问题，我只是在pylintrc文件中添加了禁用选项。就我而言，我正在研究一个小脚本，一些pylint检查有点矫枉过正。所以我禁用未定义​​的变量错误

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

通过

禁用= E0602，E0603
