重复部分抽象成一个函数，并在程序中调用该函数

这两行抽成方法。

def fun1():
    print("I want nobody nobody but you")
    print("I want nobody nobody but you")
if __name__ == '__main__':
    fun1()
    print("How can I be with another")
    print("I don't want any other")
    fun1()
    print("I want nobody nobody but you")

def show:
print('I want nobody nobody but you')
