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)

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()

我写了一个简单的进度条:

def bar(total, current, length=10, prefix="", filler="#", space=" ", oncomp="", border="[]", suffix=""):
    if len(border) != 2:
        print("parameter 'border' must include exactly 2 symbols!")
        return None

    print(prefix + border[0] + (filler * int(current / total * length) +
                                      (space * (length - int(current / total * length)))) + border[1], suffix, "\r", end="")
    if total == current:
        if oncomp:
            print(prefix + border[0] + space * int(((length - len(oncomp)) / 2)) +
                  oncomp + space * int(((length - len(oncomp)) / 2)) + border[1], suffix)
        if not oncomp:
            print(prefix + border[0] + (filler * int(current / total * length) +
                                        (space * (length - int(current / total * length)))) + border[1], suffix)

正如你所看到的，它有:条的长度，前缀和后缀，填充，空间，文本在条上100%(oncomp)和边界

这里有一个例子:

from time import sleep, time
start_time = time()
for i in range(10):
    pref = str((i+1) * 10) + "% "
    complete_text = "done in %s sec" % str(round(time() - start_time))
    sleep(1)
    bar(10, i + 1, length=20, prefix=pref, oncomp=complete_text)

正在进行中:

30% [######              ]

Out on complete:

100% [   done in 9 sec   ] 

我意识到我在游戏中迟到了，但这里是我写的一个稍微有点yum风格的(Red Hat)(这里不是100%的准确性，但如果你使用进度条来达到这个准确度，那么你就错了):

import sys

def cli_progress_test(end_val, bar_length=20):
    for i in xrange(0, end_val):
        percent = float(i) / end_val
        hashes = '#' * int(round(percent * bar_length))
        spaces = ' ' * (bar_length - len(hashes))
        sys.stdout.write("\rPercent: [{0}] {1}%".format(hashes + spaces, int(round(percent * 100))))
        sys.stdout.flush()

应该产生如下所示的结果:

Percent: [##############      ] 69%

．.． 括号保持不变，只有哈希值增加。

作为装饰器，这可能会更好。再等一天……

检查这个库:clint

根据上面的建议，我制作了进度条。

然而，我想指出一些缺点

每次刷新进度条时，它将从新一行开始 打印(‘\ r({0}){1} %’。格式('#' * progress* 10, progress)) 是这样的: [] 0% [#] 10% (# #) 20% (# # #) 30%

2.方括号“]”和右边的百分数随着“###”变长而右移。 3.如果表达式'progress / 10'不能返回整数，则会发生错误。

下面的代码将修复上面的问题。

def update_progress(progress, total):  
    print('\r[{0:10}]{1:>2}%'.format('#' * int(progress * 10 /total), progress), end='')
