Python如何像json_normalize一样扁平化json文件

def flatten_json(json_data, prefix=''):
    flattened_data = {}
    
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            new_key = prefix + '.' + key if prefix else key
            flattened_data.update(flatten_json(value, new_key))
    elif isinstance(json_data, list):
        for index, item in enumerate(json_data):
            new_key = prefix + '.' + str(index) if prefix else str(index)
            flattened_data.update(flatten_json(item, new_key))
    else:
        flattened_data[prefix] = json_data
    
    return flattened_data

import json

json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "hobbies": ["reading", "coding"]
}

flattened_data = flatten_json(json_data)
print(flattened_data)

{
    "name": "John",
    "age": 30,
    "address.street": "123 Street",
    "address.city": "New York",
    "hobbies.0": "reading",
    "hobbies.1": "coding"
}
