读写json数据

json.dumps(),json.dump,json.loads,json.load的使用

import json
d1 = [1, 2, ‘abc‘, {‘name‘: ‘s‘, ‘age‘: 18}]
d2 = {‘b‘: None, ‘a‘: 1, ‘c‘: ‘cc‘}
‘‘‘dumps()与dump()区别在于接口的不同，dump()是对文件的写操作‘‘‘
print json.dumps(d1)
print json.dumps(d2)
print json.dumps(d2, separators=[‘,‘, ‘:‘])
print json.dumps(d2, sort_keys=True)

with open(‘jsonName.json‘, ‘wb‘) as f:
    json.dump(d2, f)

‘‘‘loads()与load()区别在于接口的不同，load()是对文件的读操作‘‘‘
print json.loads(‘{"a": 1, "c": "cc", "b": null}‘)

with open(‘jsonName.json‘, ‘rb‘) as f1:
    print json.load(f1)
