Python中的带刷新的进度条实例4.3换成time.time()函数怎么做啊，各位，求各位解答一下

Answer 1

大概是这样吧

import time

scale = 50
print("执行开始".center(scale//2, '-'))
t = time.time()

for i in range(scale+1):
    a = '*' * i
    b = '.' * (scale - i)
    c = (i / scale) * 100
    print("\r{:^3.0f}% [{}->{}] {:.2f}s".format(c, a, b, time.time() - t), end='')
    time.sleep(0.05)
print("\n" + "执行结束".center(scale//2, '-'))
