# 1、检索文件夹大小的程序，要求执行方式如下
# python3
# .8
# run.py
# 文件夹
#python 3.8 run.py 文件夹
# import sys,os
# src = sys.argv[1]
# res = 0
#
# def size_of_file(file):
# global res
# for file1 in os.listdir(r"%s "%file):
# path = os.path.join(file,file1)
# print(path)
# if os.path.isfile(path):
# res += os.path.getsize(src)
# else:
# size_of_file(path)
# if os.path.isfile(r"%s"%src):
# res = os.path.getsize(src)
# else:
# size_of_file(src)
# print(res)
# 2、明天上午日考：随机验证码、模拟下载以及打印进度条、文件copy脚本
#随机验证码

#
# while recv_size < total_size:
