在python中的JSON加载问题

Question

尝试解决此链接中给出的示例但它给出了错误。 Parsing values from a JSON file?

a.json

find . -type f -exec sh -c 'echo {}; git blame {}; echo;' \; > /tmp/git_files.log

Python文件

{
    "maps": [
        {
            "id": "blabla",
            "iscategorical": "0"
        },
        {
            "id": "blabla",
            "iscategorical": "0"
        }
    ],
    "masks": {
        "id": "valore"
    },
    "om_points": "value",
    "parameters": {
        "id": "valore"
    }
}

错误

import json
from pprint import pprint

data = json.load(open('a.json'))

pprint(data)
