Why would it be written like that? It's written the way it is because that made sense to Guido.

You keep using the work iteration, I don't think you understand what it means. This:

temp['id'] = id

Is assigning to an index. That assigns a single value to a single key in the dictionary. This is plain old indexing (getting a single value out of a dictionary):

id = temp['id']

Iteration is for loops. So this would be iteration:

for key in temp:
    print(key, temp[key])

That gets all the keys out of the dictionary. Generally, you get all the key/value pairs out of the dictionary together with the items method:

for key, value in temp.items():
    print(key, value)
