Why this matters
The __all__ variable should only list valid module attributes. Listing undefined titles can cause ImportError when using wildcard imports.
__all__ Contains Only Defined NamesCheck if the __all__ list in a module contains titles that are not defined. Listing undefined titles can cause ImportError when performing wildcard imports.

Side-by-side examples engineers can pattern-match during review.
from mymodule import my_func
__all__ = ["unknown_func"] # Noncompliant: "unknown_func" is undefinedfrom mymodule import my_func
__all__ = ["my_func"]From the same buckets as this rule.
Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.
