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。

检查这个库:clint

它有很多功能，包括一个进度条:

from time import sleep  
from random import random  
from clint.textui import progress  
if __name__ == '__main__':
    for i in progress.bar(range(100)):
        sleep(random() * 0.2)

    for i in progress.dots(range(100)):
        sleep(random() * 0.2)

此链接提供了其功能的快速概述

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%

哈哈，我刚刚为此写了一整篇文章 这里的代码请记住，你不能使用unicode时做块ASCII我使用cp437

import os
import time
def load(left_side, right_side, length, time):
    x = 0
    y = ""
    print "\r"
    while x < length:
        space = length - len(y)
        space = " " * space
        z = left + y + space + right
        print "\r", z,
        y += "█"
        time.sleep(time)
        x += 1
    cls()

你就这么叫它

print "loading something awesome"
load("|", "|", 10, .01)

它看起来是这样的

loading something awesome
|█████     |

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)

import time,sys

for i in range(100+1):
    time.sleep(0.1)
    sys.stdout.write(('='*i)+(''*(100-i))+("\r [ %d"%i+"% ] "))
    sys.stdout.flush()

输出

[29 percent] ===================
