An Internet rule of thumb

(It would have been a pretty mutant Lisp. But mutating your Lisp isalmost de rigueur.)
Of course, I must include a pointer to Greenspun's Tenth Rule ofProgramming .

Python's assert is a weak debugging tool
Here's something (perhaps obvious) that recent experience has taughtme:
Python's
assertis a pretty bad debugging tool.
The problem is that a failed assert gives you almost no information,just that it did fail. Almost all the time, you need to know somethingabout what the bad values are in order to actually debug the problem,so your first step is to transform ' assert condition ' into somethinglike:
if not condition: printassert condition (The exception that proves the
