Others have already answered your questions about memory. Let me answer the question you didn't ask about style :-) Don't use "l" as a variable name, as it looks too much like 1. Better to use L, or even better, a meaningful name. Rather than convert a float 1E9 to an int at runtime, better to use an int: range(10**9) With recent versions of CPython, the compiler has a keyhole optimiser which does constant folding. For implementations of Python which don't do constant folding, 10**9 is likely to be faster than int(1E9) -- but even if it isn't, does it matter? It will be very fast one way of the other. The important thing is that 10**9 expresses the intention to use an integer in a more direct fashion than using 1E9. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
