Why this decorator can't get imported from module with "from module import *"?
decorator, import, properties, python
Solution
See if there is a variable named `__all__` defined near the top of your module. If so it will have a sequence (list or tuple) of string names assigned to it. These are the public names of the module which are imported by the `from ... import *` statement.
Without the `__all__` name defined, all names defined in a module (as well as names imported from other modules), which do not begin with an underscore, are considered to be public.
Make sure the `__all__` sequence includes the string "CachedProperty".
Problem
I have the following decorator inside a module: ``` class CachedProperty(object): """Decorator that lazy-loads the value of a property. The first time the property is accessed, the original property function is executed. The value it returns is set as the new value of that instance's property, replacing the original method. """ def __init__(self, wrapped): self.wrapped = wrapped try: self.__doc__ = wrapped.__doc__ except: pass def __get__(self, instance, instance_type=None): if instance is None: return self value = self.wrapped(instance) setattr(instance, self.wrapped.__name__, value) return value ``` I want to import this decorator and other stuff from the module like this: ``` from clang.cindex import * ``` But I'm unable to import that single decorator this way, it works if I do: ``` from clang.cindex import CachedProperty ``` then I can use `@CachedProperty`. Why can't I import this class through `*` while I'm able to import others?
