我喜欢Brian Khuu的答案，因为它简单，不需要外部包。我做了一点改动，所以我在这里添加了我的版本:

import sys
import time


def updt(total, progress):
    """
    Displays or updates a console progress bar.

    Original source: https://stackoverflow.com/a/15860757/1391441
    """
    barLength, status = 20, ""
    progress = float(progress) / float(total)
    if progress >= 1.:
        progress, status = 1, "\r\n"
    block = int(round(barLength * progress))
    text = "\r[{}] {:.0f}% {}".format(
        "#" * block + "-" * (barLength - block), round(progress * 100, 0),
        status)
    sys.stdout.write(text)
    sys.stdout.flush()


runs = 300
for run_num in range(runs):
    time.sleep(.1)
    updt(runs, run_num + 1)

它取总运行次数(total)和目前处理的运行次数(progress)，假设total >= progress。结果如下所示:

[#####---------------] 27%

你可以使用富库，它有非常好的终端样式，包括进度条。 首先执行如下命令: PIP安装丰富

来自docs的例子:

import time
from rich.progress import track

for i in track(range(20), description="Processing..."):
    time.sleep(1)  # Simulate work being done

jelde015的一个更普通的答案(当然是他的功劳)

手动更新加载条将是:

import sys
from math import *


def loadingBar(i, N, size):
    percent = float(i) / float(N)
    sys.stdout.write("\r"
                     + str(int(i)).rjust(3, '0')
                     +"/"
                     +str(int(N)).rjust(3, '0')
                     + ' ['
                     + '='*ceil(percent*size)
                     + ' '*floor((1-percent)*size)
                     + ']')

称之为:

loadingBar(7, 220, 40)

将结果:

007/220 [=                                       ]  

只要你想用当前的I值调用它。

将大小设置为条形图应有的字符数

在这里寻找等效的解决方案后，我只是为我的需求做了一个简单的进度类。我想我应该把它贴出来。

from __future__ import print_function
import sys
import re


class ProgressBar(object):
    DEFAULT = 'Progress: %(bar)s %(percent)3d%%'
    FULL = '%(bar)s %(current)d/%(total)d (%(percent)3d%%) %(remaining)d to go'

    def __init__(self, total, width=40, fmt=DEFAULT, symbol='=',
                 output=sys.stderr):
        assert len(symbol) == 1

        self.total = total
        self.width = width
        self.symbol = symbol
        self.output = output
        self.fmt = re.sub(r'(?P<name>%\(.+?\))d',
            r'\g<name>%dd' % len(str(total)), fmt)

        self.current = 0

    def __call__(self):
        percent = self.current / float(self.total)
        size = int(self.width * percent)
        remaining = self.total - self.current
        bar = '[' + self.symbol * size + ' ' * (self.width - size) + ']'

        args = {
            'total': self.total,
            'bar': bar,
            'current': self.current,
            'percent': percent * 100,
            'remaining': remaining
        }
        print('\r' + self.fmt % args, file=self.output, end='')

    def done(self):
        self.current = self.total
        self()
        print('', file=self.output)

例子:

from time import sleep

progress = ProgressBar(80, fmt=ProgressBar.FULL)

for x in xrange(progress.total):
    progress.current += 1
    progress()
    sleep(0.1)
progress.done()

将打印以下内容:

[========] 17/80 (21%) 63

使用os_sys lib:

我在许多类型的条形图中使用它，例如:

from os_sys.progress import bar as Bar
bar = Bar('progresing: ', max=20)
for i in range(20):
    #do somthing
    bar.next()
bar.finish()

你的输出将是:

procesing:  |######                          | 2/10

请在os_sys的描述中阅读更多信息

这是我的简单解决方案:

import time

def progress(_cur, _max):
    p = round(100*_cur/_max)
    b = f"Progress: {p}% - ["+"."*int(p/5)+" "*(20-int(p/5))+"]"
    print(b, end="\r")

# USAGE:
for i in range(0,101):
    time.sleep(0.1) 
    progress(i,100)

print("..."*5, end="\r")
print("Done")
