I agree that many people misuse asserts. I agree that this is a problem
for them. But I disagree that the solution is to remove what I consider
to be a useful feature, and a common one in other languages, just to
protect people from their broken code.
I prefer to see better efforts to educate them. To that end, I've taken
the liberty of sending a post to python-list at python.org describing when
to use asserts, and when not to use them:
I will continue to use my best effort to encourage good use of
assertions in Python.
