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

试试由Python界的莫扎特Armin Ronacher编写的点击库。

$ pip install click # both 2 and 3 compatible

创建一个简单的进度条:

import click

with click.progressbar(range(1000000)) as bar:
    for i in bar:
        pass 

这是它的样子:

# [###-------------------------------]    9%  00:01:14

定制您心中的内容:

import click, sys

with click.progressbar(range(100000), file=sys.stderr, show_pos=True, width=70, bar_template='(_(_)=%(bar)sD(_(_| %(info)s', fill_char='=', empty_char=' ') as bar:
    for i in bar:
        pass

自定义:

(_(_)===================================D(_(_| 100000/100000 00:00:02

还有更多的选项，请参阅API文档:

 click.progressbar(iterable=None, length=None, label=None, show_eta=True, show_percent=None, show_pos=False, item_show_func=None, fill_char='#', empty_char='-', bar_template='%(label)s [%(bar)s] %(info)s', info_sep=' ', width=36, file=None, color=None)

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

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

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()
