Keep an eye on your console for those DeprecationWarnings —they are there to help you stay ahead of the curve!
Rapidly turning a warning into a hard error can break environments. A longer warning period ensures developers see the notice without their builds immediately failing. 122982
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
Large codebases and libraries need time to refactor code that might be legacy or automatically generated. If you have ever accidentally used the bitwise
Originally, the plan was to move toward a full error or a more aggressive deprecation schedule. However, Issue #122982 proposes . This extension serves a few key purposes:
Python Development Update: Extending the Deprecation Warning for ~bool (Issue #122982)
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 .
