[ Python 常見問題 ] How can I get a list of all classes within current module in Python?

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

view plaincopy to clipboardprint?

1. # foo.py  
2. class Foo:  
3.     pass  
4.   
5. # test.py  
6. import inspect  
7. import foo  
8.   
9. for name, obj in inspect.getmembers(foo):  
10.     if inspect.isclass(obj):  
11.         print obj  

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

view plaincopy to clipboardprint?

1. # foo.py  
2. import inspect  
3.   
4. class Foo:  
5.     pass  
6.   
7. def print_classes():  
8.     for name, obj in inspect.getmembers(???): # what do I do here?  
9.         if inspect.isclass(obj):  
10.             print obj  
11.   
12. # test.py  
13. import foo  
14.   
15. foo.print_classes()  

How-To 
Try this: 

view plaincopy to clipboardprint?

1. import sys  
2. current_module = sys.modules[__name__]  

For example: 
- common/Test.py 

view plaincopy to clipboardprint?

1. class A:  
2.     def __init__(self, name):  
3.         self.name = name  
4.   
5.     def __repr__(self):  
6.         return "A-{}".format(self.name)  
7.   
8.   
9. class B:  
10.     def __init__(self, name):  
11.         self.name = name  
12.   
13.     def __repr__(self):  
14.         return "B-{}".format(self.name)  

Then you can list the class in common/Test.py this way: 

>>> import sys, inspect 
>>> from common import Test 
>>> for name, clz in inspect.getmembers(sys.modules['common.Test'], inspect.isclass): 
... print('{}\t{}'.format(name, clz('Hello'))) // Print the name of class and initialize it 
... 
A A-Hello 
B B-Hello
