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   ] 

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%

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)

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()

把我在这里找到的一些想法放在一起，加上估计的剩余时间:

import datetime, sys

start = datetime.datetime.now()

def print_progress_bar (iteration, total):

    process_duration_samples = []
    average_samples = 5

    end = datetime.datetime.now()

    process_duration = end - start

    if len(process_duration_samples) == 0:
        process_duration_samples = [process_duration] * average_samples

    process_duration_samples = process_duration_samples[1:average_samples-1] + [process_duration]
    average_process_duration = sum(process_duration_samples, datetime.timedelta()) / len(process_duration_samples)
    remaining_steps = total - iteration
    remaining_time_estimation = remaining_steps * average_process_duration

    bars_string = int(float(iteration) / float(total) * 20.)
    sys.stdout.write(
        "\r[%-20s] %d%% (%s/%s) Estimated time left: %s" % (
            '='*bars_string, float(iteration) / float(total) * 100,
            iteration,
            total,
            remaining_time_estimation
        ) 
    )
    sys.stdout.flush()
    if iteration + 1 == total:
        print 


# Sample usage

for i in range(0,300):
    print_progress_bar(i, 300)
