1、打印下载进度条

import time

total_size = 20000
recv_size = 1024
recved_size = 0
sign = 1
while sign:
    if recved_size <= total_size:
        # 模拟网络延迟
        time.sleep(1)
        # 实际接受数据长度
        # data = client.recv(1024)
        # recv_size = len(data)

        percent = recved_size / total_size

        if percent > 1:
            percent = 1
            sign = 0

        num = percent * 50

        print('\r[{:<50}]{}%'.format('=' * (int(num)), int(percent*100)), end='')

        recved_size += recv_size

        if recved_size > total_size:
            recved_size = total_size
