json.load()方法

json.load()方法

参考[1] https://docs.python.org/2/library/json.html

conversion table如下：

我们使用最多的就是将json对象转换成Python dict.

举个例子，
1.txt

{
    "filename": "/mnt/data/src/0a5ca1430d.c",
    "tokens": [
        {
            "kind": "Keyword",
            "line": 2,
            "sem": "FunctionDecl",
            "text": "int"
        },
        {
            "kind": "Identifier",
            "line": 2,
            "sem": "FunctionDecl",
            "sym": {
                "id": "c:@F@main",
                "kind": "FunctionDecl",
                "type": "int ()"
            },
            "text": "main"
        }
    ]
}

test.py

import json
if __name__ == '__main__':
    with open("1.txt","rb") as json_object:
        json_data = json.load(json_object)
    print(type(json_data))
    filename = json_data['filename']
    tokens = json_data['tokens']
    print(filename)
    print(type(tokens))
    print(len(tokens))
    print(tokens[0])
    print(tokens[1])

运行test.py输出结果如下

可见json.load()方法就是将json文件对象转换为了python dict.
