Get the current time in seconds since the start of the universe (10am on January 1st 1970 on Linux systems, it may be slightly different on Windows or Macintosh): >>> import time >>> time.time() 1273588356.8070121 Get the current time in a more human-readable fashion: >>> time.ctime() 'Wed May 12 00:33:22 2010' Get the elapsed time: >>> start = time.time() # save the current time >>> for i in range(1000): # do some work ... pass ... >>> elapsed = time.time() - start >>> print "work took %f seconds" % elapsed work took 0.015870 seconds See the documentation for the time module: http://docs.python.org/library/time.html That's a bit technical and newbie-unfriendly, so you might also like to read this: http://effbot.org/librarybook/time.htm although it's very old and parts of it are obsolete. -- Steven D'Aprano _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
