python字符串类在源代码中的位置 [英] Location of python string class in the source code

问题描述

我正在考虑为特定字符串重载 + 运算符，因此我考虑将字符串类子类化，然后将代码添加到新类中。但是我想先看一下标准的字符串类，但是似乎找不到...愚蠢的吗？

I'm looking into overloading the + operator for a certain string so I was thinking of subclassing the string class then adding the code in the new class. However I wanted to take a look at the standard string class first but I can't seem to find it... stupid eh?

有人可以指出路吗？甚至是源代码的在线文档。

Can anyone point the way? Even online documentation of the source code.

推荐答案

此处。主要实现在 Objects / stringobject.c 。不过，子类化 str 可能不是您想要的。我倾向于这里的构图。有一个带有字符串字段的对象，并且具有特殊的行为。

It's documented here. The main implementation is in Objects/stringobject.c. Subclassing str probably isn't what you want, though. I would tend to prefer composition here; have an object with a string field, and special behavior.
