今天我遇到了以下pylint错误:
invalid-all-object (E0604):
Invalid object %r in __all__, must contain only strings Used when an invalid (non-string) object occurs in __all__.
我很好奇为什么直接公开对象被认为是不正确的?
最佳答案
因为它应该是名称的列表,而不是值:
If the list of identifiers is replaced by a star (
'*'
), all public names defined in the module are bound in the local namespace for the scope where theimport
statement occurs.The public names defined by a module are determined by checking the module’s namespace for a variable named
__all__
; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in__all__
are all considered public and are required to exist. If__all__
is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ('_'
).__all__
should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module). [Language Reference]
关于python - 为什么 __all__ 应该只包含字符串对象?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41860105/
