Iterating Over Object Attributes in Python

object_iteration.md

Given an object in Python, we can iterate over its attributes (much as we might iterate over keys in a dictionary) by using the following method. In this example, we convert an object into a list of the attribute contents of the object.

[data.__dict__[key] for key in data.__dict__.iterkeys()]

So, given a class,

class Example():

  def __init__():
    pass

We can create an instance and assign attributes:

ex = Example()
ex.a = 1
ex.b = 2
ex.c = 3

Then we find that:

contents = [ex.__dict__[key] for key in ex.__dict__.iterkeys()]
# --> contents = [1, 2, 3]
