assert-false (B011)#
Derived from the flake8-bugbear linter.

(python -O), making assert False an unreliable means of
raising an AssertionError.
Instead, raise an AssertionError directly.
Example#
Use instead:
Fix safety#
This rule's fix is marked as unsafe, as changing an assert to a
raise will change the behavior of your program when running in
optimized mode (python -O).
