json

JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式

json.dumps: Python obj to JSON string
json.loads: coded JSON string to Python object

import json
data={'info_type': 'PING',
          'log_files': 'my other log files',
          'machine_name': 'machine b',
          'radial_ID': 'sampleID'}
dataStr=json.dumps(data)

obj = [[1,2,3],123,123.123,'abc',{'key1':(1,2,3),'key2':(4,5,6)}]
encodedjson = json.dumps(obj)

repr(obj)
#"[[1, 2, 3], 123, 123.123, 'abc', {'key1': (1, 2, 3), 'key2': (4, 5, 6)}]"
print(encodedjson)
#[[1, 2, 3], 123, 123.123, "abc", {"key2": [4, 5, 6], "key1": [1, 2, 3]}]

You will find in the process of json encoding, list and tuple are both converted to array in JSON.
