Walkthrough
The changes update the handling of base class duplication and negative cache logic in the abstract base class (ABC) metaclass implementation, and simplify the import fallback logic for ABCMeta in the abc module. No public API or exported entity declarations were altered.
Changes
| File(s) |
Change Summary |
| Lib/_py_abc.py |
Removed deduplication of base classes in ABCMeta; adjusted negative cache check in instancecheck. |
| Lib/abc.py |
Simplified import fallback logic by removing ModuleNotFoundError-specific handling. |
Poem
In the warren of code, some bases repeat,
Now left untouched, they quietly greet.
The cache checks are lighter, imports more neat,
With Pythonic abstraction, our changes complete.

100-103: Fix indentation issue in multi-line conditional.
The static analysis correctly identifies an indentation problem. Line 102 should be indented further to properly align with the multi-line conditional expression.
