# 今日作业：
# 1、 编写日志装饰器，实现功能如：一旦函数f1执行，则将消息2017-07-21 11:12:11 f1 run写入到日志文件中，日志文件路径可以指定
# 注意：时间格式的获取
# import time
# time.strftime('%Y-%m-%d %X')
# import time
# time.strftime('%Y-%m-%d %X')
# import time
#
# def outter(func):
# def wrapper(*args, **kwargs):
# res = func(*args, **kwargs)
# file = input('请输入日志路径：')
# with open(file, 'at', encoding='utf-8') as f:
# t = time.strftime('%Y-%m-%d %H:%M:%S')
# n =f'{t} f1 run
'
# f.write(n)
# return res
# return wrapper
#
# @outter
# def index(x, y):
# time.sleep(1)
# print('index==>',x,y)
#
# index(1, 2)
# 2、基于迭代器的方式，用while循环迭代取值字符串、列表、元组、字典、集合、文件对象
# # names = 'asdfasfasfd'
# # names = [1, 2, 3, 4]
# # names = (1, 2, 3, 4)
# # names=['lqz_sb','yj_sb','jason_sb','egon']
# # names = {1, 2, 3, 4}
# # name = iter(names)
# # while True:
# # try:
# # print(next(name))
# # except:
# # StopIteration
# # break
# with open('access.log', 'r', encoding='utf-8') as names:
# name = iter(names)
# while True:
# try:
# print(next(name))
# except:
# StopIteration
# break
# 3、自定义迭代器实现range功能
# def my_range(start, stop, step = 1):
# while start < stop:
# yield start
# start += step
#
# g = my_range(1,5)
# for i in g:
# print(i)
#
#
# ==================== 本周选做作业如下 ====================
# 编写小说阅读程序实现下属功能
# # 一：程序运行开始时显示
# 0 账号注册
# 1 登录功能
# 2 充值功能
# 3 阅读小说
# 2.1、账号注册
# - 针对文件db.txt，内容格式为："用户名:密码:金额" 完成注册功能
# # 五：为功能2.2、3.2编写记录日志的装饰器，日志格式为："时间 用户名 操作(充值or消费) 金额"
#
# # 三：文件story_class.txt存放类别与小说文件路径，如下,读出来后可用eval反解出字典
# {"0":{"0":["倚天屠狗记.txt",3],"1":["沙雕英雄转.txt",10]},"1":{"0":["令人羞耻的爱.txt",6],"1":["二狗的妻子与大草原的故事.txt",5]},}
#
# 3.1、用户登录成功后显示如下内容，根据用户选择，显示对应品类的小说编号、小说名字、以及小说的价格
# """
# 0 玄幻武侠
# 1 都市爱情
# 2 高效养猪36技
# """
# 3.2、用户输入具体的小说编号，提示是否付费，用户输入y确定后，扣费并显示小说内容，如果余额不足则提示余额不足
#
# # 四：为功能2.2、3.1、3.2编写认证功能装饰器，要求必须登录后才能执行操作
