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   ] 

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='')

Tqdm:在你的循环中添加一个进度表:

>>> import time
>>> from tqdm import tqdm
>>> for i in tqdm(range(100)):
...     time.sleep(1)
... 
|###-------| 35/100  35% [elapsed: 00:35 left: 01:05,  1.00 iters/sec]

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)

    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   ] 

写入'\r'将把光标移回行首。

这将显示一个百分比计数器:

import time
import sys

for i in range(100):
    time.sleep(1)
    sys.stdout.write("\r%d%%" % i)
    sys.stdout.flush()
