head()的具体实现：

def head(self, n=5):
        '''
        Return the first `n` rows.
        This function returns the first `n` rows for the object based
        on position. It is useful for quickly testing if your object
        has the right type of data in it.
        Parameters
        ----------
        n : int, default 5
            Number of rows to select.
        Returns
        -------
        obj_head : same type as caller
            The first `n` rows of the caller object.
        '''
        return self.iloc[:n]

head() 不传参数时，默认n是5，返回前五行
如果指定返回多少行，比如10行，传具体行数 head(10)
