Sure, and floating point arithmetic is inherently imprecise and doesn't follow the associative laws for either addition or multiplication. There are times when we have to be aware of those details. Usually, though, we want to act as if they represent the mathematical reals, and we read Python statements involving floats as if they were mathematical statements involving reals. When possible, we write in a style where this doesn't cause problems, use double precision to decrease rounding errors in long calculations, etc. Similarly we occasionally have to be aware of the procedural nature of Python list comprehensions, but most of the time we think of them in terms of the mathematical abstraction they are designed to resemble. -- https://mail.python.org/mailman/listinfo/python-list
