如何在python中解析json字符串？

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.

Answer 1

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.
