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   ] 

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()

好吧，这里是工作的代码，我在发布之前测试了它:

import sys
def prg(prog, fillchar, emptchar):
    fillt = 0
    emptt = 20
    if prog < 100 and prog > 0:
        prog2 = prog/5
        fillt = fillt + prog2
        emptt = emptt - prog2
        sys.stdout.write("\r[" + str(fillchar)*fillt + str(emptchar)*emptt + "]" + str(prog) + "%")
        sys.stdout.flush()
    elif prog >= 100:
        prog = 100
        prog2 = prog/5
        fillt = fillt + prog2
        emptt = emptt - prog2
        sys.stdout.write("\r[" + str(fillchar)*fillt + str(emptchar)*emptt + "]" + str(prog) + "%" + "\nDone!")
        sys.stdout.flush()
    elif prog < 0:
        prog = 0
        prog2 = prog/5
        fillt = fillt + prog2
        emptt = emptt - prog2
        sys.stdout.write("\r[" + str(fillchar)*fillt + str(emptchar)*emptt + "]" + str(prog) + "%" + "\nHalted!")
        sys.stdout.flush()

优点:

20个字符条(每5个字符对应1个字符) 自定义填充字符 自定义空字符 暂停(任何低于0的数字) 完成(100及100以上的任何数字) 进度计数(0-100(以下和以上用于特殊功能)) 条形图旁边的百分数，这是一条单线

缺点:

仅支持整数(但可以通过将除法改为整数除法来支持整数，因此只需将prog2 = prog/5更改为prog2 = int(prog/5))

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]

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)

并且，为了添加到堆中，这里有一个你可以使用的对象:

将以下内容添加到新文件progressbar.py中

import sys

class ProgressBar(object):
    CHAR_ON  = '='
    CHAR_OFF = ' '

    def __init__(self, end=100, length=65):
        self._end = end
        self._length = length
        self._chars = None
        self._value = 0

    @property
    def value(self):
        return self._value
    
    @value.setter
    def value(self, value):
        self._value = max(0, min(value, self._end))
        if self._chars != (c := int(self._length * (self._value / self._end))):
            self._chars = c
            sys.stdout.write("\r  {:3n}% [{}{}]".format(
                int((self._value / self._end) * 100.0),
                self.CHAR_ON  * int(self._chars),
                self.CHAR_OFF * int(self._length - self._chars),
            ))
            sys.stdout.flush()

    def __enter__(self):
        self.value = 0
        return self

    def __exit__(self, *args, **kwargs):
        sys.stdout.write('\n')

可以包含在您的程序中:

import time
from progressbar import ProgressBar

count = 150
print("starting things:")

with ProgressBar(count) as bar:
    for i in range(count + 1):
        bar.value += 1
        time.sleep(0.01)

print("done")

结果:

starting things:
  100% [=================================================================]
done

这可能有点“夸张”，但如果经常使用，就很方便了。
