Question

How do you get a list of all variables in a class thats iteratable? Kind of like locals(), but for a class

class Example(object):
    bool143 = True
    bool2 = True
    blah = False
    foo = True
    foobar2000 = False

    def as_list(self)
       ret = []
       for field in XXX:
           if getattr(self, field):
               ret.append(field)
       return ",".join(ret)

this should return

>>> e = Example()
>>> e.as_list()
bool143, bool2, foo

Answer 1

dir(obj)

gives you all attributes of the object.
You need to filter out the members from methods etc yourself:

class Example(object):
    bool143 = True
    bool2 = True
    blah = False
    foo = True
    foobar2000 = False

example = Example()
members = [attr for attr in dir(example) if not callable(getattr(example, attr)) and not attr.startswith("__")]
print members   

Will give you:

['blah', 'bool143', 'bool2', 'foo', 'foobar2000']
