python3 json文件规范化问题(normalize)

Question

现有一个内容不规范的json文件（books.json），需要用Python的json_normalize()函数将其标准化

file=open('books.json','r')

text=file.read()

text=json.loads（text）

json_normalize(text,'book')

运行出现错误“

raise JSONDecodeError("Expecting value", s, err.value) from None

JSONDecodeError: Expecting value

”

是怎么回事呢

json文件的内容是：

[{"writer":"Mark Ross","nationality":"USA","books":[

        {"title":"XML Cookbook","price":23.56},

        {"title":"Python Fundamentals","price":50.70},

        {"title":"The NumPy library","price":12.30}]

    },

    {"writer":"Barbara Bracket","nationality":"UK","books":[

           { "title":"Java Enterprise","price":28.60},

           {"title":"HTML5","price":31.35},

           {"title":"Python for Dummies","price":28.00}

           ]

    }]
