Anything equivalent to cassert in C++?

[Peng Yu]

There are some assertion code (testing if a condition is false, if it
is false, raise an Error object) in my python, which is useful when I
test my package. But such case would never occur when in the produce
code. If I keep them in if statement, it will take some runtime. I'm
wondering what is the practice that take care of the assertion code in
python.

You should be very careful not to put unit tests in asserts because that
prevents you from testing your application under optimization.
