这是我当前的代码，当我运行它时，我遇到了一些错误......我不确定它们是什么。
Traceback (most recent call last):

请您参考如下方法:
变量 booksread 不在它使用的任何函数的范围内 nestediffunction、eliffunction 和 simpleiffunction .修改这两个函数，以便您可以接受 booksread 变量作为参数，并且可以相应地从 main 传递它。
def simpleiffunction(booksread ):
....
def nestediffunction(booksread ):
....
def eliffunction(booksread ):
....
