Python: JSON - string indices must be integers-CodePudding

input JSON file format.

{
    "Orange_2001": {
        "dir": "/home/fruits/orange.check",
        "path": "/home/fruits/orange",
        "name": "Orange"
    },
    "Apple_345": {
        "dir": "/home/fruits/apple.check",
        "path": "/home/fruits/apple",
        "name": "Apple"
    }
}

Im trying to convert it to below format, but facing TypeError: string indices must be integers

{
    "Orange": { "/home/fruits/orange.check": "/home/fruits/orange" },

    "Apple": { "/home/fruits/apple.check": "/home/fruits/apple" }
}

Code snippet :

fruits = {}
    with open('fruits.json', 'r') as data:
        metadata = json.load(data)
        for key, value in metadata.items():
            fruits[metadata[key]['name']] = {}
            fruits[metadata[key]['name']] = metadata[key]['name']['dir']
            fruits[metadata[key]['name']] = metadata[key]['name']['path']

Am I missing something silly ?

CodePudding user response：

You made a typo:

metadata[key]['name']['dir']

Should be:

metadata[key]['dir']

(and the same for the line below)

Also you can replace metadata[key] with value everywhere, that's the point of iterating with .items() !

Additionally, your code wouldn't produce the desired output right now, as you would get : {"Orange" : "home/fruits/orange", "Apple" : "home/fruits/apple"}. You should replace the three lines in your for loop by:

fruits[value['name']] = {value['dir']: value['path']}
