import sys
def progresssbar():

            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

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。

Tqdm:在你的循环中添加一个进度表:

>>> import time
>>> from tqdm import tqdm
>>> for i in tqdm(range(100)):
...     time.sleep(1)
... 
|###-------| 35/100  35% [elapsed: 00:35 left: 01:05,  1.00 iters/sec]

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

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()

写入'\r'将把光标移回行首。

这将显示一个百分比计数器:

import time
import sys

for i in range(100):
    time.sleep(1)
    sys.stdout.write("\r%d%%" % i)
    sys.stdout.flush()
