一种简单的方法解决多个数字的乘法和除法

def multiply_or_divide(numbers, operation):
    if operation == "multiply":
        result = 1
    elif operation == "divide":
        result = numbers[0]
    
    for num in numbers:
        if operation == "multiply":
            result *= num
        elif operation == "divide":
            result /= num
    
    return result

# 示例用法
numbers = [2, 3, 4]
operation = "multiply"
result = multiply_or_divide(numbers, operation)
print("乘法结果:", result)

operation = "divide"
result = multiply_or_divide(numbers, operation)
print("除法结果:", result)
