3.30作业

# 1、检索文件夹大小的程序，要求执行方式如下
# python3.8   run.py
# import os
# import sys
#
# path = os.path.dirname(__file__)
# size = 0
# def get_dir_size(path):
#     for line in os.listdir(path):
#         path2 = os.path.join(path, line)
#         if os.path.isfile(path2):
#             global size
#             size += os.path.getsize(path2)
#         else:
#             get_dir_size(path2)
#     return  size
#
#
# res=get_dir_size(path)
# print(res)

# 文件夹
# 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
# import random
#
# def make_code(size=4):
#     res=''
#     for i in range(size):
#         s1=chr(random.randint(65,90))
#         s2=str(random.randint(0,9))
#         res+=random.choice([s1,s2])
#     return res
#
# print(make_code(6))
