import json

json_input = '{"Brand-SWT": [{"userId": "Brian", "Currency": "CNY"}, {"userId": "David", "Currency": "USD"} ] }'

try:
    decoded = json.loads(json_input)
    for x in decoded['Brand-SWT']:
        print x['userId']
        print x['Currency']
except (ValueError,KeywordError,TypeError):
    print"json format error"

目前自己大概写了这些，但是如果json_input为 response 结果。。。

那代码怎么 改呢？ import request      ,  json_input = request.get (????)
