rspec/rules/S5807/python/rule.adoc

Developers may define a list named ``++__all__++`` in a module to limit the names imported from it by wildcard imports (``++from mymodule import *++``). This list can only reference defined names, otherwise an ``++AttributeError++`` will be raised when the module is imported.


== Noncompliant Code Example

----
from mymodule import my_func

__all__ = ["unknown_func"]  # Noncompliant. "unknown_func" is undefined
----


== Compliant Solution

----
from mymodule import my_func

__all__ = ["my_func"]
----
