Certain web applications, everything from wget to downloader for X has this nifty feature I'd like to accomplish in python.
Its the progress bar/time elapsed/time remaining scheme Filename | Progress | Speed (kB/s) | T/Elapsed | T/Remaining ---------------------------------------------------------------------------- blah.bin |------>45% | 56.6 | 02:39 | 02:45 file2.bz2 |--->33% | 35.0 | 05:22 | 11:24 etc |-------->60% | 47.5 | 00:14 | 00:08 (could be either text or a gui..) So where would one begin to accomplish this sort of thing efficiently? I've searched the web and there are plenty of resources on network programming in python, but how could I 1) keep track of download speed 2) calculate t/elapsed/remaining 3) output that to a progress bar w/o spawning countless threads to do the many calculations and avoid eating up the entire CPU. This seems like it would require a lot of resources and easily go out of sync with the real world file transfer. To compound problems, I have a very limited understanding of threads and using multiple threads that rely on eachother doesn't make very much sense. Can anyone point me in the right direction? -thanks in advance -- http://mail.python.org/mailman/listinfo/python-list
