模块作业

# 1、检索文件夹大小的程序，要求执行方式如下
# python3
# .8
# run.py
# 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
#
# 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))

# import time
# def progress(percent):
#     if percent > 1:
#         percent = 1
#     res = int(50 * percent) * "#"
#     print('
[%-50s] %d%%' % (res, int(100 * percent)), end='')
#     
# recv_size=0
# total_size=1025011
# 
# while recv_size < total_size:
#     time.sleep(0.01) # 下载了1024个字节的数据
# 
#     recv_size+=1024 # recv_size=2048
# 
#     # 打印进度条
#     # print(recv_size)
#     percent = recv_size / total_size  # 1024 / 333333
#     progress(percent)
    

# import sys

# 
# file_path = sys.argv
