The 'arbitrary argument' list is an another way to pass arguments to a function. In the function body, these arguments will be wrapped in a tuple and it can be defined with *args construct. Before this variable,
这样,我们终于可以用python语法给类instance增加新成员了。 这几乎就是python User defined class的全貌了。说是几乎,因为我们还漏了两个东西,一个是attribute access逻辑,一个是descriptor。后者可以用来实现很多高级python特性,比如给class或者成员属性指定类型(TypedAttribute P55),实现static and class methods (P58)。

A pandas user-defined function (UDF)—also known as vectorized UDF—is a user-defined function that uses Apache Arrow to transfer data and pandas to work with the data. pandas UDFs allow vectorized operations that can increase performance up to 100x compared to row-at-a-time Python UDFs. ...
