oop – Print all properties of a Python Class

In this simple case you can use vars():

an = Animal()
attrs = vars(an)
# {kids: 0, name: Dog, color: Spotted, age: 10, legs: 2, smell: Alot}
# now dump this in some way or another
print(, .join(%s: %s % item for item in attrs.items()))

If you want to store Python objects on the disk you should look at shelve — Python object persistence.

Another way is to call the dir() function (see https://docs.python.org/2/library/functions.html#dir).

a = Animal()
dir(a)   
>>>
[__class__, __delattr__, __dict__, __doc__, __format__, __getattribute__,
 __hash__, __init__, __module__, __new__, __reduce__, __reduce_ex__, 
 __repr__, __setattr__, __sizeof__, __str__, __subclasshook__, 
 __weakref__, age, color, kids, legs, name, smell]

Note, that dir() tries to reach any attribute that is possible to reach.

Then you can access the attributes e.g. by filtering with double underscores:

attributes = [attr for attr in dir(a) 
              if not attr.startswith(__)]

This is just an example of what is possible to do with dir(), please check the other answers for proper way of doing this.

Maybe you are looking for something like this?

    >>> class MyTest:
        def __init__ (self):
            self.value = 3
    >>> myobj = MyTest()
    >>> myobj.__dict__
    {value: 3}
