How to parse json string in python?

Question

Below code is running fine.

 import json
 json_data = '{"Detail":" Rs. 2000 Topup Rs.1779.99 Talktime","Amount":"2000","Validity":"Unlimited"}'
 json_parsed = json.loads(json_data)
 print(json_parsed['Detail'])
 print(json_parsed['Amount'])
 print(json_parsed['Validity'])

How to parse below json string? and How to display all values also?

json_data = '[{"Detail":" Rs. 2000 Topup Rs.1779.99 Talktime","Amount":"2000","Validity":"Unlimited"},{"Detail":" Rs. 1900 Topup Rs.1690.99 Talktime","Amount":"1900","Validity":"Unlimited"}]'

Please help me.

• karthikr: so what is the problem you are facing? Did you try your code against the json string?
• UnholySheep: The only difference is that the second string is an array of objects - so what exactly is your problem?
• Venkatesh Panabaka: I don't how to parse this string [{"Detail":" Rs. 2000 Topup Rs.1779.99 Talktime","Amount":"2000","Validity":"Unlimited"},{"Detail":" Rs. 1900 Topup Rs.1690.99 Talktime","Amount":"1900","Validity":"Unlimited"}]
• Venkatesh Panabaka: why giving down votes to my question? Don't know how to do that because of that only raised question. Actually i am very new to python. After i done lot of R&D only i got the first answer.

This json string is an array of objects, as opposed to a single object.

You'd parse it the same way with the json module, however instead of getting a single dictionary you would get a list of dictionaries.

you'd be able to display as so:

import json
json_data = '[{"Detail":" Rs. 2000 Topup Rs.1779.99 Talktime","Amount":"2000","Validity":"Unlimited"},{"Detail":" Rs. 1900 Topup Rs.1690.99 Talktime","Amount":"1900","Validity":"Unlimited"}]'
# convert to python data structure
d_list = json.loads(json_data)
# loop through the list
for d in d_list:
 # use get for safety
 print d.get('Detail')
 print d.get('Amount')

Regardless of the parsing language, python, javascript, php and so on, any json string or subset of a json string that has objects wrapped in [brackets] will be an array, and will need to be handled in a similar (language specific) fashion.
