Convert JSON string in python
When we develop a Web service, we may use a JSON-based Web service protocol. If you use the Python language to develop, its extension module can directly handle messages in JSON format. For example, Python's JSON module introduced in Python 2.6 provides a default JSON encoder and decoder, but of course you can install and use other JSON encoders/decoders.
The code snippet below is an example of parsing JSON in Python
import json
json_input = '{ "one": 1, "two": { "list": [ {"item":"A"},{"item":"B"} ] } }'
try:
decoded = json.loads(json_input)
# pretty printing of json-formatted string
print json.dumps(decoded, sort_keys=True, indent=4)
print "JSON parsing example: ", decoded['one']
print "Complex JSON parsing example: ", decoded['two']['list'][1]['item']
except (ValueError, KeyError, TypeError):
print "JSON format error"The following is the result printed by the example
{
"one": 1,
"two": {
"list": [
{
"item": "A"
},
{
"item": "B"
}
]
}
}
JSON parsing example: 1
Complex JSON parsing example: B
