我如何看待Python对象内部? [英] How do I look inside a Python object?

问题描述

我开始使用Python在各种项目中进行编码(包括Django Web开发和Panda3D游戏开发).

I'm starting to code in various projects using Python (including Django web development and Panda3D game development).

为了帮助我理解发生了什么，我想基本上在Python对象内部看"看它们如何打勾-像它们的方法和属性一样.

To help me understand what's going on, I would like to basically 'look' inside the Python objects to see how they tick - like their methods and properties.

所以说我有一个Python对象，我需要打印出什么内容?那有可能吗?

So say I have a Python object, what would I need to print out its contents? Is that even possible?

推荐答案

Python具有强大的自省功能.

Python has a strong set of introspection features.

看看以下内置函数:

• type()
• dir()
• id()
• getattr()
• hasattr()
• globals()
• locals()
• callable()

• type()
• dir()
• id()
• getattr()
• hasattr()
• globals()
• locals()
• callable()

type()和dir()分别对于检查对象的类型及其属性集特别有用.

type() and dir() are particularly useful for inspecting the type of an object and its set of attributes, respectively.
