This blog post addresses in the CPython repository, which focuses on extending the deprecation warning period for bitwise inversion on boolean types in Python.

In Python, booleans are a subclass of integers. When you apply the bitwise NOT operator ( ~ ) to a boolean: ~True (which is ~1 ) evaluates to -2 . ~False (which is ~0 ) evaluates to -1 .

If you have ever accidentally used the bitwise inversion operator ( ~ ) on a Python boolean, you might have noticed it behaves in a way that is technically correct but logically confusing. As Python continues to refine its syntax for better clarity, Issue #122982 marks a small but important step in how the language handles these edge cases. The Problem: Why ~True Isn't False

Keep an eye on your console for those DeprecationWarnings —they are there to help you stay ahead of the curve!

Python’s evolution is often about making the "obvious" way to do things the only way to do things. While Issue #122982 might seem like a minor administrative tweak in the CPython GitHub, it reflects the core philosophy of maintaining a stable, readable, and developer-friendly language.
