How Python invokes the command-line progress bar

This example describes how Python invokes the command-line progress bar. Share to everyone for your reference. The specific analysis is as follows:

The key point is that the output ' \ R ' character allows the cursor to return to the beginning of a line, and the output will overwrite the original content.

Import Timeimport sysdef progress_test ():  bar_length=20  for percent in Xrange (0, +):    hashes = ' # ' * INT (per cent/100.0 * bar_length)    spaces = "* (Bar_length-len (hashes))    Sys.stdout.write (" \rpercent: [%s]%d%% "% (Hashe s + spaces, percent))    Sys.stdout.flush ()    time.sleep (1) progress_test ()
