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)):
...

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)

一个非常简单的解决方案是将以下代码放入循环中:

把这个放在你的文件的主体(即顶部):

import sys

把这个放在你的循环体中:

sys.stdout.write("-") # prints a dash for each iteration of loop
sys.stdout.flush() # ensures bar is displayed incrementally

还有很多教程等着你去谷歌。

在Python命令行运行这个命令(不是在任何IDE或开发环境中):

>>> import threading
>>> for i in range(50+1):
...   threading._sleep(0.5)
...   print "\r%3d" % i, ('='*i)+('-'*(50-i)),

在我的Windows系统上运行良好。

根据上面的答案和其他类似的关于CLI进度条的问题，我想我得到了一个普遍的答案。请登录https://stackoverflow.com/a/15860757/2254146查看。

总之，代码是这样的:

import time, sys

# update_progress() : Displays or updates a console progress bar
## Accepts a float between 0 and 1. Any int will be converted to a float.
## A value under 0 represents a 'halt'.
## A value at 1 or bigger represents 100%
def update_progress(progress):
    barLength = 10 # Modify this to change the length of the progress bar
    status = ""
    if isinstance(progress, int):
        progress = float(progress)
    if not isinstance(progress, float):
        progress = 0
        status = "error: progress var must be float\r\n"
    if progress < 0:
        progress = 0
        status = "Halt...\r\n"
    if progress >= 1:
        progress = 1
        status = "Done...\r\n"
    block = int(round(barLength*progress))
    text = "\rPercent: [{0}] {1}% {2}".format( "#"*block + "-"*(barLength-block), progress*100, status)
    sys.stdout.write(text)
    sys.stdout.flush()
