需要在每个子json数组中递归地插入新的键值对

def insert_key_value(json_array, key, value):
    if isinstance(json_array, list):
        for element in json_array:
            insert_key_value(element, key, value)
    elif isinstance(json_array, dict):
        json_array[key] = value
        for key, value in json_array.items():
            insert_key_value(value, key, value)

# 示例用法
json_array = [
    {"name": "John", "age": 25},
    {"name": "Alice", "age": 30},
    {"name": "Bob", "age": 35}
]

insert_key_value(json_array, "city", "New York")

print(json_array)

[
    {"name": "John", "age": 25, "city": "New York"},
    {"name": "Alice", "age": 30, "city": "New York"},
    {"name": "Bob", "age": 35, "city": "New York"}
]
