#python基本學習-實現FastPower進度條

#progress bar

import time
scale = 50
print("執行開始".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"+"執行結束".center(scale//2, '-'))

根據需要選擇不同的設計函數，本例選擇的函數為FastPower，開始運行慢，后面運行快

運行結果：

 

 文本進度條的設計函數如下：
