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
|█████     |

还有很多教程等着你去谷歌。

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%

python终端进度条代码

import sys
import time

max_length = 5
at_length = max_length
empty = "-"
used = "%"

bar = empty * max_length

for i in range(0, max_length):
    at_length -= 1

    #setting empty and full spots
    bar = used * i
    bar = bar+empty * at_length

    #\r is carriage return(sets cursor position in terminal to start of line)
    #\0 character escape

    sys.stdout.write("[{}]\0\r".format(bar))
    sys.stdout.flush()

    #do your stuff here instead of time.sleep
    time.sleep(1)

sys.stdout.write("\n")
sys.stdout.flush()

Progressbar2是一个很好的基于ascii的命令行progressbar库 导入的时间 进口progressbar

bar = progressbar.ProgressBar()
for i in bar(range(100)):
    time.sleep(0.02)
bar.finish()

TQDM是progressbar2的替代方案，我认为它用于pip3，但我不确定

from tqdm import tqdm
for i in tqdm(range(10000)):
...

import sys
def progresssbar():
         for i in range(100):
            time.sleep(1)
            sys.stdout.write("%i\r" % i)

progressbar()

注意:如果你在交互式拦截器中运行这个，你会得到额外的数字打印出来
