it seems that range() can be really slow: the following program will run, and the last line shows how long it ran for:
import time startTime = time.time() a = 1.0 for i in range(0, 30000): if i in range (0, 10000): a += 1 if not i % 1000: print i print a, " ", round(time.time() - startTime, 1), "seconds" --------------------------------- the last line of output is --------------------------------- 10001.0 22.8 seconds so if i change the line if i in range (0, 10000): to if i >= 0 and i < 10000: the the last line is 10001.0 0.2 seconds so approximately, the program ran 100 times faster! or is there an alternative use of range() or something similar that can be as fast? -- http://mail.python.org/mailman/listinfo/python-list
