So, 0.0 would be cached, and the 414m+384m would be from the list itself, right? I tried, >>> data = [(1.0/i) for i in xrange(1,100000000)] And the memory consumption was the big one. Grant, the 800 MB is taken by ONE 0.0, and a list of zillion positions. Furthermore, I did: >>> for x in xrange(100000000): ... i = random() And the memory didn't increase. Grant, take note that there's no gc issue, the numbers stay alive because the list itself is pointing to them. Closing this as invalid.
