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

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。

哈哈，我刚刚为此写了一整篇文章 这里的代码请记住，你不能使用unicode时做块ASCII我使用cp437

import os
import time
def load(left_side, right_side, length, time):
    x = 0
    y = ""
    print "\r"
    while x < length:
        space = length - len(y)
        space = " " * space
        z = left + y + space + right
        print "\r", z,
        y += "█"
        time.sleep(time)
        x += 1
    cls()

你就这么叫它

print "loading something awesome"
load("|", "|", 10, .01)

它看起来是这样的

loading something awesome
|█████     |

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)

这将给你一些像:[##########]100%

函数从Greenstick 2.7:

def printProgressBar (iteration, total, prefix = '', suffix = '',decimals = 1, length = 100, fill = '#'):

percent = ("{0:." + str(decimals) + "f}").format(100 * (iteration / float(total)))
filledLength = int(length * iteration // total)
bar = fill * filledLength + '-' * (length - filledLength)
print'\r%s |%s| %s%% %s' % (prefix, bar, percent, suffix),
sys.stdout.flush()
# Print New Line on Complete                                                                                                                                                                                                              
if iteration == total:
    print()

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]
