尝试安装这个包:pip install progressbar2:

import time
import progressbar

for i in progressbar.progressbar(range(100)):
    time.sleep(0.02)

进度栏 GitHub： https://github.com/WoLpH/python-progressbar

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='')

安装tqdm。(pip安装tqdm) 使用方法如下:

import time
from tqdm import tqdm
for i in tqdm(range(1000)):
    time.sleep(0.01)

这是一个10秒的进度条，输出如下内容:

47%|██████████████████▊                     | 470/1000 [00:04<00:05, 98.61it/s]

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

把我在这里找到的一些想法放在一起，加上估计的剩余时间:

import datetime, sys

start = datetime.datetime.now()

def print_progress_bar (iteration, total):

    process_duration_samples = []
    average_samples = 5

    end = datetime.datetime.now()

    process_duration = end - start

    if len(process_duration_samples) == 0:
        process_duration_samples = [process_duration] * average_samples

    process_duration_samples = process_duration_samples[1:average_samples-1] + [process_duration]
    average_process_duration = sum(process_duration_samples, datetime.timedelta()) / len(process_duration_samples)
    remaining_steps = total - iteration
    remaining_time_estimation = remaining_steps * average_process_duration

    bars_string = int(float(iteration) / float(total) * 20.)
    sys.stdout.write(
        "\r[%-20s] %d%% (%s/%s) Estimated time left: %s" % (
            '='*bars_string, float(iteration) / float(total) * 100,
            iteration,
            total,
            remaining_time_estimation
        ) 
    )
    sys.stdout.flush()
    if iteration + 1 == total:
        print 


# Sample usage

for i in range(0,300):
    print_progress_bar(i, 300)
