Unreasonable memory usage under linux with a simple loop
Hi all, I'm new to here and python. When I tried the code below to test python's speed... I found that python use more than 1.5G memory to run this and cost several minutes And this happened only under my linux os. Both jython and python... Is there something wrong with python under linux or my code? Thanks! a = 0 for i in range(1): a = a + 1 print a -- http://mail.python.org/mailman/listinfo/python-list

You are right...Thanks Since my MAC have too much RAM..I didn't notice it -- http://mail.python.org/mailman/listinfo/python-list
