> import json
> data = {'a':1,'b':2,'c':3}
> json.dumps(data)
'{"a": 1, "b": 2, "c": 3}'

>json.dumps(data,indent=4) //4为所及的数

>json.dumps(data,separators(',',':'))
{"a":1,"b":[1,2,3],"c":3}

>s = json.dumps(data,nsure_ascii=False)

> with open(r'C:\Users\test.json','w') as f:
...   json.dump(data,f)
...
>with open(r'C:\Users\test.json','r') as f:
...  f.read()
...
'{"a": 1, "b": 2, "c": 3}'

> s = json.dumps(data)
> s
'{"a": 1, "b": 2, "c": 3}'
> json.loads(s)
{'a': 1, 'b': 2, 'c': 3}
