试试由Python界的莫扎特Armin Ronacher编写的点击库。

$ pip install click # both 2 and 3 compatible

创建一个简单的进度条:

import click

with click.progressbar(range(1000000)) as bar:
    for i in bar:
        pass 

这是它的样子:

# [###-------------------------------]    9%  00:01:14

定制您心中的内容:

import click, sys

with click.progressbar(range(100000), file=sys.stderr, show_pos=True, width=70, bar_template='(_(_)=%(bar)sD(_(_| %(info)s', fill_char='=', empty_char=' ') as bar:
    for i in bar:
        pass

自定义:

(_(_)===================================D(_(_| 100000/100000 00:00:02

还有更多的选项，请参阅API文档:

 click.progressbar(iterable=None, length=None, label=None, show_eta=True, show_percent=None, show_pos=False, item_show_func=None, fill_char='#', empty_char='-', bar_template='%(label)s [%(bar)s] %(info)s', info_sep=' ', width=36, file=None, color=None)

python模块progressbar是一个不错的选择。 下面是我的典型代码:

import time
import progressbar

widgets = [
    ' ', progressbar.Percentage(),
    ' ', progressbar.SimpleProgress(format='(%(value_s)s of %(max_value_s)s)'),
    ' ', progressbar.Bar('>', fill='.'),
    ' ', progressbar.ETA(format_finished='- %(seconds)s  -', format='ETA: %(seconds)s', ),
    ' - ', progressbar.DynamicMessage('loss'),
    ' - ', progressbar.DynamicMessage('error'),
    '                          '
]

bar = progressbar.ProgressBar(redirect_stdout=True, widgets=widgets)
bar.start(100)
for i in range(100):
    time.sleep(0.1)
    bar.update(i + 1, loss=i / 100., error=i)
bar.finish()

检查这个库:clint

它有很多功能，包括一个进度条:

from time import sleep  
from random import random  
from clint.textui import progress  
if __name__ == '__main__':
    for i in progress.bar(range(100)):
        sleep(random() * 0.2)

    for i in progress.dots(range(100)):
        sleep(random() * 0.2)

此链接提供了其功能的快速概述

写入一个\r到控制台。这是一个“回车”，它使它之后的所有文本都在行首回显。喜欢的东西:

def update_progress(progress):
    print '\r[{0}] {1}%'.format('#'*(progress/10), progress)

这将给你一些像:[##########]100%

它只有不到10行代码。

要点如下:https://gist.github.com/vladignatyev/06860ec2040cb497f0f3

import sys


def progress(count, total, suffix=''):
    bar_len = 60
    filled_len = int(round(bar_len * count / float(total)))

    percents = round(100.0 * count / float(total), 1)
    bar = '=' * filled_len + '-' * (bar_len - filled_len)

    sys.stdout.write('[%s] %s%s ...%s\r' % (bar, percents, '%', suffix))
    sys.stdout.flush()  # As suggested by Rom Ruben

函数从Greenstick 2.7:

def printProgressBar (iteration, total, prefix = '', suffix = '',decimals = 1, length = 100, fill = '#'):

percent = ("{0:." + str(decimals) + "f}").format(100 * (iteration / float(total)))
filledLength = int(length * iteration // total)
bar = fill * filledLength + '-' * (length - filledLength)
print'\r%s |%s| %s%% %s' % (prefix, bar, percent, suffix),
sys.stdout.flush()
# Print New Line on Complete                                                                                                                                                                                                              
if iteration == total:
    print()
