在python中获取json/字典中的所有键路径组合

def get_key_paths(data, parent_key='', separator='.'):
    key_paths = []
    if isinstance(data, dict):
        for k, v in data.items():
            new_key = f"{parent_key}{separator}{k}" if parent_key else k
            key_paths.extend(get_key_paths(v, new_key, separator))
    elif isinstance(data, list):
        for i, v in enumerate(data):
            new_key = f"{parent_key}{separator}{i}" if parent_key else str(i)
            key_paths.extend(get_key_paths(v, new_key, separator))
    else:
        key_paths.append(parent_key)
    return key_paths

# 示例用法
data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    },
    "hobbies": ["reading", "coding"]
}

key_paths = get_key_paths(data)
for key_path in key_paths:
    print(key_path)

name
age
address.street
address.city
