这个错误发生在第22行,提示`'tuple' object has no attribute 'insert'`,意思是元组对象没有`insert`属性。根据代码,这个元组对象是`rows`,这个错误说明你尝试在元组对象上调用了`insert`方法,但元组是不可变对象,没有`insert`方法。
为了解决这个问题,你需要将`rows`从元组对象转变为列表对象。你可以在获取`rows`的地方使用`list`方法将其转变为列表,比如:
```python
rows = list(cursor.fetchall())
```
这样就可以将元组对象转换为列表对象,然后就可以在列表上使用`insert`方法了。

AttributeError Traceback (most recent call last
This error occurs when you try to access an attribute or method that does not exist in the object you are using.
To fix this error, you should check the spelling and syntax of the attribute or method you are trying to access. Make sure that it exists in the object you are using. If you are not sure, you can use the `dir()` function to list all the attributes and methods of the object.
If the attribute or method is supposed to exist but is still giving you an error, it could be a problem with the object itself. In this case, you may need to check the documentation or seek help from the developer community.
AttributeError Traceback (most recent call last)
This error occurs when you try to access an attribute or method that does not exist in the object you are working with. It is a common error in Python and can be caused by various reasons such as typos, incorrect usage of variables or objects, or missing imports.
To fix this error, you should carefully check your code and ensure that all the attributes and methods you are calling actually exist in the object you are working with. If you are still unable to find the error, you can try printing out the object and its attributes to see what is going wrong.
