如何在python中获取类的所有属性

Question

I have this class in python defined like this

class MyClass(object):
   @property
   def property1(self):
       # type: () -> pb.data.Property1

   @property
   def property2(self):
       # type: () -> pb.data.Property2

How can I use reflection to read all the properties that the class has and then make a map from the property name to its class

something like

{"property1":"pb.data.Property1", "property2":"pb.data.Property2"}

Remember that the first line in each property is a comment. Is there a clear way to do it?

You can use inspect.getmembers to get all the attribute values. Hopefully below code will help you out.

import inspect
class MyClass(object):
    @property
    def property1(self):
        return 'pb.data.Property1'

    @property
    def property2(self):
        return 'pb.data.Property2'

    def get_attributes(self):
        attributes = inspect.getmembers(self, predicate=lambda a: not(inspect.isroutine(a)))
        return {d[0]:d[1] for d in attributes if not(d[0].startswith('__') and d[0].endswith('__'))}


MyClass().get_attributes()

Output : {'property1': 'pb.data.Property1', 'property2': 'pb.data.Property2'}
