Removing handlers from python's logging loggers

Question

I am playing with Python\'s logging system. I have noticed a strange behavior while removing handlers from a Logger object in a loop. Namely, my for loop removes all but one

Answer 1

This isn't logger-specific behaviour. Never mutate (insert/remove elements) the list you're currently iterating on. If you need, make a copy. In this case testLogger.handlers = [] should do the trick.
