How to return new Object every time by calling same dict value in Python?

I am trying to set class definition for dictionary element that every time by getting dict element new object should appear.

Example:

types = {}
types[first_type] = FirstType()
types[second_type] = SecondType()

And by setting types[first_type] I have to get new FirstType():

some_var = new types[first_type] # this is illegal statement.

How can I achieve this in Python?
