如何在 Python 中获取当前模块中所有类的列表? [英] How can I get a list of all classes within current module in Python?

问题描述

我见过很多人从一个模块中提取所有类的例子，通常是这样的:

I've seen plenty of examples of people extracting all of the classes from a module, usually something like:

# foo.py
class Foo:
    pass

# test.py
import inspect
import foo

for name, obj in inspect.getmembers(foo):
    if inspect.isclass(obj):
        print obj

棒极了.

但我不知道如何从 current 模块中获取所有类.

But I can't find out how to get all of the classes from the current module.

# foo.py
import inspect

class Foo:
    pass

def print_classes():
    for name, obj in inspect.getmembers(???): # what do I do here?
        if inspect.isclass(obj):
            print obj

# test.py
import foo

foo.print_classes()

这可能是很明显的事情，但我什么也没找到.谁能帮帮我?

This is probably something really obvious, but I haven't been able to find anything. Can anyone help me out?

推荐答案

试试这个:

import sys
current_module = sys.modules[__name__]

在您的上下文中:

import sys, inspect
def print_classes():
    for name, obj in inspect.getmembers(sys.modules[__name__]):
        if inspect.isclass(obj):
            print(obj)

甚至更好:

clsmembers = inspect.getmembers(sys.modules[__name__], inspect.isclass)

因为 inspect.getmembers() 需要一个谓词.

Because inspect.getmembers() takes a predicate.
