给每个函数写一个记录日志的功能.

# 功能要求: 每一次调用函数之前, 要将函数名称, 时间节点记录到log的日志中.
# 所需模块:
# import time
#
# def logger(fn):
#     def inner(*args, **kwargs):
#         # fn.__name__ # 函数名字
#         f = open("log", mode="a", encoding="utf-8")
#         f.write("在%s, 访问了%s函数
" % (time.strftime("%Y-%m-%d %H:%M:%S"), fn.__name__))
#         ret = fn(*args, **kwargs)
#         return ret
#     return inner
#
#
# @logger
# def chi():
#     print("wusir特别能吃")
# @logger
# def he():
#     print("太白特别能和")
# @logger
# def shui():
#     print("太黑特别能睡")
#
#
# chi()
# chi()
# he()
# chi()
# shui()
# shui()
