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()

https://pypi.python.org/pypi/tqdm

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)):
...

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()

并且，为了添加到堆中，这里有一个你可以使用的对象:

将以下内容添加到新文件progressbar.py中

import sys

class ProgressBar(object):
    CHAR_ON  = '='
    CHAR_OFF = ' '

    def __init__(self, end=100, length=65):
        self._end = end
        self._length = length
        self._chars = None
        self._value = 0

    @property
    def value(self):
        return self._value
    
    @value.setter
    def value(self, value):
        self._value = max(0, min(value, self._end))
        if self._chars != (c := int(self._length * (self._value / self._end))):
            self._chars = c
            sys.stdout.write("\r  {:3n}% [{}{}]".format(
                int((self._value / self._end) * 100.0),
                self.CHAR_ON  * int(self._chars),
                self.CHAR_OFF * int(self._length - self._chars),
            ))
            sys.stdout.flush()

    def __enter__(self):
        self.value = 0
        return self

    def __exit__(self, *args, **kwargs):
        sys.stdout.write('\n')

可以包含在您的程序中:

import time
from progressbar import ProgressBar

count = 150
print("starting things:")

with ProgressBar(count) as bar:
    for i in range(count + 1):
        bar.value += 1
        time.sleep(0.01)

print("done")

结果:

starting things:
  100% [=================================================================]
done

这可能有点“夸张”，但如果经常使用，就很方便了。

安装tqdm。(pip安装tqdm) 使用方法如下:

import time
from tqdm import tqdm
for i in tqdm(range(1000)):
    time.sleep(0.01)

这是一个10秒的进度条，输出如下内容:

47%|██████████████████▊                     | 470/1000 [00:04<00:05, 98.61it/s]

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

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()
