#python基本学习-实现FastPower进度条

#progress bar

import time
scale = 50
print("执行开始".center(scale//2, ‘-‘))
start = time.perf_counter()
for i in range(scale + 1):
    ratio = (i / scale)
    fastPower = pow(ratio + (1 - ratio) / 2, 8)
    movedBar = ‘*‘ * int(scale * fastPower)
    residualBar = ‘.‘ * int(scale * (1 - fastPower))
    percentFastPower = fastPower * 100
    dur = time.perf_counter() - start
    print("\r{:^3.0f}%[{}->{}]{:.2f}s".format(percentFastPower, movedBar, residualBar, dur), end = ‘‘)
    time.sleep(0.1)
print("\n"+"执行结束".center(scale//2, ‘-‘))

根据需要选择不同的设计函数，本例选择的函数为FastPower，开始运行慢，后面运行快

运行结果：

 文本进度条的设计函数如下：
