Python Simple progress bar Example __python

Recently need to write a small script python, with some small knowledge, hurriedly take time to record. not deep but often used.

Two progress bar example, the copy can be run:

# coding=utf-8

Import sys
import time

# width:   percent: Percent
def progress (width, percent):
    Print "\r%s%d%%"% ('%%-%ds '% width)% (width * percent/100 * ' = '), percent),
    if percent >=: print
  
   sys.stdout.flush ()


# example One, 0%--100%
def demo1 ():
    for I in Xrange (m):
        Progress (i + 1))
        Time.sleep (0.1)


# #  Example two, periodic load
def demo2 ():
    i = n = m = n
    > 0:
        print "\t\t\ t%s \ r "% (i *" = "),
        i = (i + 1)%
        Time.sleep (0.1)
        N-= 1


demo1 ()
Demo2 ()
  

Provides a simple asynchronous progress bar written by yourself that can be opened before a time-consuming operation and then stopped after a time-consuming operation.

Import time
import thread
import sys

class Progress:
    def __init__ (self):
        Self._flag = False
    def timer (self):
        i =
        self._flag:
            print "\t\t\t%s \ r"% (i * "="),
            Sys.stdout.flush ()
            i = (i + 1%
            time.sleep (0.05)
        print "\t\t\t%s\n"% (* "="),
        Thread.exit_thread ()
    def start (self): C15/>self._flag = True
        thread.start_new_thread (Self.timer, ())
    def Stop (self):
        Self._flag = False
        Time.sleep (1)

Usage:

progress = Progress ()
Progress.start ()
time.sleep (5)
progress.stop ()
