What version are you using?  As far as I can test, it has become a syntax error since 3.10. Here is the result with the latest 3.11 alpha

> python
Python 3.11.0a2 (tags/v3.11.0a2:e2b4e4b, Nov  5 2021, 20:00:05) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> del __debug__
  File "<stdin>", line 1
SyntaxError: cannot delete __debug__
>>> exit()
