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:

https://mail.python.org/pipermail/python-list/2013-November/660401.html

I will continue to use my best effort to encourage good use of 
assertions in Python.
