Question

>>> my_str = 'name'
>>> my_object[my_str] # won't work because it not a dictionary :)

Answer 2

>>> myobject.__dict__[my_str]
'stuff'

Answer 3

You cannot run __dict__-approach altogether. What will always work

getattr(myobject, my_str)

If you need type access, just define a class with an overloaded operator index.

Answer 4

You can provide operator support []for objects of your class by defining a small family of methods - getitem and setitem , basically. See the following few entries in the docs for some others to implement, for full support.
