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   ] 

我正在使用来自reddit的进度。我喜欢它，因为它可以在一行中打印每一项的进度，而且它不应该从程序中删除打印输出。

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。

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

以下是我的Python 3解决方案:

import time
for i in range(100):
    time.sleep(1)
    s = "{}% Complete".format(i)
    print(s,end=len(s) * '\b')

'\b'是反斜杠，对应字符串中的每个字符。 这在Windows cmd窗口内不起作用。
