is_private property ¤

is_private: bool

Whether this object/alias is private (starts with _) but not special.

is_public property ¤

is_public: bool

Whether this object is considered public.

In modules, developers can mark objects as public thanks to the __all__ variable. In classes however, there is no convention or standard to do so.

Therefore, to decide whether an object is public, we follow this algorithm:

  • If the object's public attribute is set (boolean), return its value.
  • If the object is listed in its parent's (a module) __all__ attribute, it is public.
  • If the parent (module) defines __all__ and the object is not listed in, it is private.
  • If the object has a private name, it is private.
  • If the object was imported from another module, it is private.
  • Otherwise, the object is public.

is_special property ¤

is_special: bool

Whether this object/alias is special ("dunder" attribute/method, starts and end with __).

is_subpackage property ¤

is_subpackage: bool

Whether this object is a subpackage.

is_wildcard_exposed property ¤

is_wildcard_exposed: bool

Whether this object/alias is exposed to wildcard imports.

To be exposed to wildcard imports, an object/alias must:

  • be available at runtime
  • have a module as parent
  • be listed in __all__ if __all__ is defined
  • or not be private (having a name starting with an underscore)

Special case for Griffe trees: a submodule is only exposed if its parent imports it.

Returns:

  • bool

    True or False.
