I love assert

I get the impression that most Pythonistas aren't as habituated with assert statements as I am. Is that just a misimpression on my part? If not, is there a good reason to assert less with Python than other languages?

As far as I can tell, Python supports assert perfectly well. When run with the optimization flagging, the asserts are truly removed.

I think one needs to take care with some basic assert coding - it's not a substitute for unit tests, it doesn't absolve you of normal exception responsibilities, and, most of all, it should be used for passive inspection and not action. But given these guidelines, I still find it very useful as "active comments".
