Python 3.x 中的加载栏

  • 772

我想制作一个类似于下载包文件或安装它们apt时的加载栏。 不知何故，有必要删除这些线条，我一直在寻找这个，但许多脚本由于某种原因无法正常工作。Linux

python

  2. 就个人而言，我确实喜欢这样（不使用模块）：

    import time

for percent in range(100):
    s = f"[{(percent // 10) * '■'}"
    s += f"{(10 - (percent // 10)) * '○'}] "
    s += f"{percent}"
    print(s, end="\r")
    time.sleep(0.1)

>>> [■■■■■■■○○○] 78

    s 被分成几行以便于阅读。事实上，所有东西都可以收集在一行中

  3. 该代码不是我的，而是从我使用的互联网上窃取的。没有额外的库 1 功能

    import time
def printProgressBar (iteration, total, prefix = '', suffix = '', decimals = 1, length = 100, fill = '█', printEnd = "\r"):
    """
    Call in a loop to create terminal progress bar
    @params:
        iteration   - Required  : current iteration (Int)
        total       - Required  : total iterations (Int)
        prefix      - Optional  : prefix string (Str)
        suffix      - Optional  : suffix string (Str)
        decimals    - Optional  : positive number of decimals in percent complete (Int)
        length      - Optional  : character length of bar (Int)
        fill        - Optional  : bar fill character (Str)
        printEnd    - Optional  : end character (e.g. "\r", "\r\n") (Str)
    """
    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), end = printEnd)
    # Print New Line on Complete
    if iteration == total:
        print()
# A List of Items
items = list(range(0, 57))
l = len(items)
# Initial call to print 0% progress
printProgressBar(0, l, prefix = 'Progress:', suffix = 'Complete', length = 50)
for i, item in enumerate(items):
    # Do stuff...
    time.sleep(0.1)
    # Update Progress Bar
    printProgressBar(i + 1, l, prefix = 'Progress:', suffix = 'Complete', length = 50)

  4. 试试看

    import time

from progress.bar import IncrementalBar

mylist = [1,2,3,4,5,6,7,8]

bar = IncrementalBar('Countdown', max = len(mylist))

for item in mylist:
    bar.next()
    time.sleep(1)

bar.finish()
