python create list from text file

Question

Hi I have big text file and I want to read the file in python and save the data on list. the structure of the file is like this

[{"address":"office1","id":"3311"},{"address":"office2","id":"3322"}]
[{"address":"office3","id":"3312"},{"address":"office4","id":"3323"}]

I want to save the first line in one list and the second line in different list. Can you please explain how to do it.

Please show us what have you tried and what the expected output? — Vishnu Upadhyay, Dec 01 '14 at 12:50

file.txt

[{"address":"office1","id":"3311"},{"address":"office2","id":"3322"}]
[{"address":"office3","id":"3312"},{"address":"office4","id":"3323"}]

code:

import ast
lists = []
for line in open('file.txt'):
    lists.append(ast.literal_eval(line.strip()))

>>> lists
[[{'id': '3311', 'address': 'office1'}, {'id': '3322', 'address': 'office2'}], [{'id': '3312', 'address': 'office3'}, {'id': '3323', 'address': 'office4'}]]
