编程时偶然发现的,就多测试了几次,似乎即便模型能正确列出优先级顺序表,它依然会固执地认为^运算符应该先于+运算。
Qwen2-7B-Instruct-GPTQ-Int4在这个问题也出现类似错误。
client = OpenAI( api_key=openai_api_key, base_url=openai_api_base, ) chat_response = client.chat.completions.create( model="Qwen2-7B-Instruct-GPTQ-Int4", messages=[ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "python中,^运算符和+运算符优先级是什么样的,5^3+2在python中如何计算,这里^是位运算不是幂?"}, ] ) print("Chat response:", chat_response.choices[0].message.content)
输出:
Chat response: 在 Python 中,运算符的优先级是固定的。对比 ^ 和 + 运算符的优先级:
^
+
+ 运算符属于算术运算符。在 Python 中,它的优先级高于位运算符,因此 a + b 表示加法。 ^ 运算符是位运算符,表示按位异或操作。在算术运算符的优先级中,它位于乘法和除法之后,但优先级高于赋值运算符(如 =)。 因此,表达式 5^3+2 应该首先执行位运算 5^3,然后执行加法运算。具体计算步骤如下: 首先计算 5^3: 二进制表示:5 是 0101,3 是 0011。 按位异或:0101 ^ 0011 = 0110。 结果是 6。 接着执行加法运算 6+2: 结果是 8。 因此,5^3+2 的计算结果是 8。
a + b
=
因此,表达式 5^3+2 应该首先执行位运算 5^3,然后执行加法运算。具体计算步骤如下:
5^3+2
5^3
首先计算 5^3:
5
0101
3
0011
0101 ^ 0011 = 0110
6
接着执行加法运算 6+2:
6+2
8
因此,5^3+2 的计算结果是 8。
实际结果应该是先计算+,最终得到0。
