下面是我使用@Mark-Rushakoff的解决方案制作的一些东西。自适应调整到终端宽度。

from time import sleep
import os
import sys
from math import ceil

l = list(map(int,os.popen('stty size','r').read().split()))
col = l[1]
col = col - 6

for i in range(col):
    sys.stdout.write('\r')
    getStr = "[%s " % ('='*i)
    sys.stdout.write(getStr.ljust(col)+"]"+"%d%%" % (ceil((100/col)*i)))
    sys.stdout.flush()
    sleep(0.25)
print("")

你可以使用\r(回车)。演示:

import sys
total = 10000000
point = total / 100
increment = total / 20
for i in xrange(total):
    if(i % (5 * point) == 0):
        sys.stdout.write("\r[" + "=" * (i / increment) +  " " * ((total - i)/ increment) + "]" +  str(i / point) + "%")
        sys.stdout.flush()

在尝试了Mark Rushakoff的解决方案后，我今天看到了这个帖子

from time import sleep
import sys

for i in range(21):
sys.stdout.write('\r')
# the exact output you're looking for:
sys.stdout.write("[%-20s] %d%%" % ('='*i, 5*i))
sys.stdout.flush()
sleep(0.25)

我可以说这在使用python 3.4.3 64位的W7-64上工作得很好，但仅限于本机控制台。但是，当使用spyder 3.0.0dev的内置控制台时，换行符仍然/再次出现。由于我花了一些时间来弄清楚，我想在这里报告这一观察结果。

对于Python 3.6，以下工作为我更新输出内联:

for current_epoch in range(10):
    for current_step) in range(100):
        print("Train epoch %s: Step %s" % (current_epoch, current_step), end="\r")
print()

在这里你可以使用以下代码作为函数:

def drawProgressBar(percent, barLen = 20):
    sys.stdout.write("\r")
    progress = ""
    for i in range(barLen):
        if i < int(barLen * percent):
            progress += "="
        else:
            progress += " "
    sys.stdout.write("[ %s ] %.2f%%" % (progress, percent * 100))
    sys.stdout.flush()

使用.format:

def drawProgressBar(percent, barLen = 20):
    # percent float from 0 to 1. 
    sys.stdout.write("\r")
    sys.stdout.write("[{:<{}}] {:.0f}%".format("=" * int(barLen * percent), barLen, percent * 100))
    sys.stdout.flush()

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。

下面是这个函数的一个副本，但是为了适合你的风格进行了修改:

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 = 20 # 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()
