如何列出Python 2.5模块中的方法？

I'm trying to use a Python library written in C that has no documentation of any kind. I want to use introspection to at least see what methods and classes are in the modules. Does somebody have a function or library I can use to list the functions (with argument lists) and classes (with methods and member variables) within a module?

我正在尝试使用用C编写的Python库,它没有任何文档。我想使用内省来至少看看模块中有哪些方法和类。有人有一个函数或库我可以用来列出模块中的函数(带参数列表)和类(带方法和成员变量)吗?

I found this article about Python introspection, but I'm pretty sure it doesn't apply to Python 2.5. Thanks for the help.

我发现这篇关于Python内省的文章,但我很确定它不适用于Python 2.5。谢谢您的帮助。

Here are some things you can do at least:

以下是您至少可以做的一些事情:

import module

print dir(module) # Find functions of interest.

# For each function of interest:
help(module.interesting_function)
print module.interesting_function.func_defaults

Mark Pilgrim's chapter 4, which you mention, does actually apply just fine to Python 2.5 (and any other recent 2.* version, thanks to backwards compatibility). Mark doesn't mention help, but I see other answers do.

Mark Pilgrim的第4章,你提到,确实适用于Python 2.5(以及任何其他最近的2. *版本,这要归功于向后兼容性)。马克没有提到帮助,但我看到其他答案。

One key bit that nobody (including Mark;-) seems to have mentioned is inspect, an excellent module in Python's standard library that really helps with advanced introspection.

没人(包括Mark ;-)似乎提到的一个关键点是inspect,这是Python标准库中的一个很好的模块,它真正有助于高级内省。

Just this is pretty good too:

这也很不错:

import module
help(module)

It will print the docstring for the module, then list the contents of the module, printing their docstrings too.

它将打印模块的docstring,然后列出模块的内容,也打印他们的文档字符串。

The dir() functions shows all members a module has.

dir()函数显示模块具有的所有成员。
