python之json读写

#将字典转json并写入文件
import json
i=3
j=5
a={‘a‘:i,‘b‘:j}
js=json.dumps(a)
print(js)

with open("/Users/binwang/Downloads/test/result.json", "w") as fp:
    fp.write(js)

----------------------------------------------------------------------

#读取json文件并转换为dict

with open(os.path.abspath(os.path.dirname(__file__)) + ‘/metadata_center_v2.json‘) as r:
    data = json.loads(r.read())
