In this case, the program is written to gobble up memory, and the operating system kills it. To “circumvent” that behaviour surely reveals the problem: that the operating system isn't handling processes very well. > > By the way: this is CPython 2.7.8. > > If you use xrange() instead of range() then you will get an iterator > which will return each of the numbers in turn without any need to > create an enormous list of all of them. If you use Python 3 instead of the obsolescent Python 2, the ‘range’ callable has this sensible behaviour by default. -- \ “Corporation, n.
