執(zhí)行結(jié)果：
I am doing some boring work before a_func()
I am the function which need some decoration to remove my foul smell
im am doing some boring work after a_func()
# __name__屬性正確了
a_function_requiring_decoration
小結(jié)
通過from functools import wraps可以解決裝飾器語法改變函數(shù)屬性name的問題汉嗽，wraps的原理不再分析篙耗。
