Python关于print的操作(倒计时、转圈显示、进度条)

num = 20
for i in range(num):
    print("#")

import time

for i in range(num):
    print("#", end="", flush=True)
    time.sleep(0.1)

import time
for i in range(5, 0, -1):
    print("\r倒计时{}秒！".format(i), end="", flush=True)
    time.sleep(1)
print("\r倒计时结束！")

import time

    list = ["\\", "|", "/", "—"]
    index = i % 4
    print("\r程序正在运行 {}".format(list[index]), end="")
