有人可以寫一個簡單的Python舊樣式類和新樣式類的例子嗎？

Question

雖然有幾篇關於新課程的文章與舊課程有關，但我無法看到具有舊/新風格的基本示例。

Answer 1

唯一的語法不同的是，新式類的對象繼承：

class Old: 
    ... 

class New(object): 
    .... 

Answer 2

我相信this wiki post是你在找什麼：

The minor syntactic difference is that New Style Classes happen 
to inherit from object. 

class Old1: 
    ... 

class Old2(Old1, UserDict): # Assuming UserDict is still old-style 
    ... 

vs 

class New1(object): 
    ... class New2(New1): 
    ... class New3(Old1, New2): 
    ... class New4(dict, Old1): # dict is a newstyle class
