如何在多维数组中获取以字符串开头的数组键？

def get_arrays_with_prefix(arr, prefix):
    result = []
    for key, value in arr.items():
        if isinstance(value, dict):
            result.extend(get_arrays_with_prefix(value, prefix))
        elif isinstance(value, list):
            for item in value:
                if isinstance(item, dict):
                    result.extend(get_arrays_with_prefix(item, prefix))
        if isinstance(key, str) and key.startswith(prefix):
            result.append(value)
    return result

# 示例多维数组
data = {
    "array1": [
        {"key1": "value1"},
        {"key2": "value2"},
        {"key3": "value3"}
    ],
    "array2": [
        {"key4": "value4"},
        {"key5": "value5"},
        {"key6": "value6"}
    ],
    "array3": [
        {"key7": "value7"},
        {"key8": "value8"},
        {"key9": "value9"}
    ]
}

# 获取以"array"开头的数组键
result = get_arrays_with_prefix(data, "array")
print(result)

[
    [
        {"key1": "value1"},
        {"key2": "value2"},
        {"key3": "value3"}
    ],
    [
        {"key4": "value4"},
        {"key5": "value5"},
        {"key6": "value6"}
    ],
    [
        {"key7": "value7"},
        {"key8": "value8"},
        {"key9": "value9"}
    ]
]
