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

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]

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()

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。

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()

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。
