如何对列表中的所有字典进行数学运算，并返回最高值的name key？

def calculate_highest_name_key(dictionaries):
    highest_value = float('-inf')  # 初始化最高值为负无穷大
    highest_name_key = None  # 初始化最高值的name key为None

    for dictionary in dictionaries:
        value = dictionary.get('value')  # 假设需要进行数学运算的值的key为'value'
        operation = dictionary.get('operation')  # 假设进行数学运算的操作的key为'operation'

        if operation == 'addition':
            result = highest_value + value
        elif operation == 'subtraction':
            result = highest_value - value
        elif operation == 'multiplication':
            result = highest_value * value
        elif operation == 'division':
            result = highest_value / value
        else:
            continue  # 如果操作不支持，则跳过当前字典

        if result > highest_value:
            highest_value = result
            highest_name_key = dictionary.get('name')  # 假设name key为'name'

    return highest_name_key
