Named dictionary in python

I did some research on how to use named array from PHP in python, while i found the following code example as they said can be done with dictionary. 

shows = [
   {"id": 1, "name": "Sesaeme Street"},
   {"id": 2, "name": "Dora The Explorer"},
]

Source: Portion of code getting from here

Reference: Python references

But how could i adding a new value through a loop? While the references shown on how to adding single value by simply shows['key']="value" but i can't linking both of them. Can anyone please show me how to add the value into this dictionary through a loop?

For example: 

for message in messages: 
            myvariable inside having two field
            - Message
            - Phone number

Update May i know how could i loop them out to display after aped list into dictionary? Thanks!

In short, you can do (list comprehension)

message_informations = [{"message": m.message, "phone": m.phone} for m in messages]

If you want to assing an id for each message_information and store in a dictionary (dict comprehension)

{_id: {"message": m.message, "phone": m.phone} for _id, m in enumerate(messages)}

You should be adding the dictionary into an array like :

friends = []
for message in messages:
  dict = {"message" : message.message, "phone" : message.phone }
  friends.append(dict)

to loop again, you can do it this way :

for friend in friends:
  print "%s - %s" % (friend["message"], friend["phone"])

Effectively your example is a list of dictionaries, in PHP terms array of associative arrays.

To add an item you can do:

shows.append({ "id" : 3, "name" : "House M.D."})

[] denotes a list, or an array.

{} denotes a dictionary or an associative array.
