Python USES the progressbar module to display the progress bar

This article illustrates Python's use of progressbar module to display progress bar function. To share for your reference, the details are as follows:

progressbar installation:

pip install progressbar

Use 1

# -*- coding=utf-8 -*-
import time
from progressbar import *
total = 1000
def dosomework():
  time.sleep(0.01)
progress = ProgressBar()
for i in progress(range(1000)):
  dosomework()

Display effect:

[

5% |### |
100% |#########################################################################|

]

Use 2

# -*- coding=utf-8 -*-
from __future__ import division
import sys, time
from progressbar import *
total = 1000
def dosomework():
  time.sleep(0.01)
pbar = ProgressBar().start()
for i in range(1000):
  pbar.update(int((i / (total - 1)) * 100))
  dosomework()
pbar.finish()

Display effect:

[

39% |############################## |
100% |#############################################################################|

]

Use 3

# -*- coding=utf-8 -*-
import time
from progressbar import *
total = 1000
def dosomework():
  time.sleep(0.01)
widgets = ['Progress: ',Percentage(), ' ', Bar('#'),' ', Timer(),
      ' ', ETA(), ' ', FileTransferSpeed()]
pbar = ProgressBar(widgets=widgets, maxval=10*total).start()
for i in range(total):
  # do something
  pbar.update(10 * i + 1)
  dosomework()
pbar.finish()

Display effect:

[

Progress: 3% |### | Elapsed Time: 0:00:15 ETA: 0:09:02 919.67 B/s
Progress: 100% |###################################################################################| Elapsed Time: 0:10:10 Time: 0:10:10 917.42 B/s

]

widgets Optional parameters Meaning:

'Progress: ': Sets the text displayed in front of the progress bar
Percentage() : Displays the percentage
Bar('#') : Sets the progress bar shape
ETA() : Displays estimated remaining time
Timer() : Displays the elapsed time
