import time,sys

for i in range(100+1):
    time.sleep(0.1)
    sys.stdout.write(('='*i)+(''*(100-i))+("\r [ %d"%i+"% ] "))
    sys.stdout.flush()

输出

[29 percent] ===================

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

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%

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]

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)

我写了一个简单的进度条:

def bar(total, current, length=10, prefix="", filler="#", space=" ", oncomp="", border="[]", suffix=""):
    if len(border) != 2:
        print("parameter 'border' must include exactly 2 symbols!")
        return None

    print(prefix + border[0] + (filler * int(current / total * length) +
                                      (space * (length - int(current / total * length)))) + border[1], suffix, "\r", end="")
    if total == current:
        if oncomp:
            print(prefix + border[0] + space * int(((length - len(oncomp)) / 2)) +
                  oncomp + space * int(((length - len(oncomp)) / 2)) + border[1], suffix)
        if not oncomp:
            print(prefix + border[0] + (filler * int(current / total * length) +
                                        (space * (length - int(current / total * length)))) + border[1], suffix)

正如你所看到的，它有:条的长度，前缀和后缀，填充，空间，文本在条上100%(oncomp)和边界

这里有一个例子:

from time import sleep, time
start_time = time()
for i in range(10):
    pref = str((i+1) * 10) + "% "
    complete_text = "done in %s sec" % str(round(time() - start_time))
    sleep(1)
    bar(10, i + 1, length=20, prefix=pref, oncomp=complete_text)

正在进行中:

30% [######              ]

Out on complete:

100% [   done in 9 sec   ]
