ypeError: 'builtin_function_or_method' object is not subscriptable

这个错误通常发生在尝试对一个内置函数或方法进行切片操作时。内置函数或方法是不可切片的,因此会引发TypeError异常。可能的原因是你误将一个内置函数或方法当作了可切片的对象来使用。
要解决这个问题,你需要检查你的代码并确定是否正确使用了可切片的对象。请确保你要切片的对象是一个支持切片操作的类型,例如字符串、列表或元组。如果你确定你的对象是可切片的,并且仍然遇到这个错误,请检查你在代码中对该对象进行的操作,确保没有误将内置函数或方法当作了可切片的对象来使用。

builtin_function_or_method' object is not subscriptable
This error message typically occurs when you try to use square brackets to access an element of an object that is not subscriptable, i.e., it does not support indexing.
For example, if you try to use square brackets to access an element of a built-in function or method in Python, you will get this error message:
```
>>> len[1, 2, 3]
TypeError: 'builtin_function_or_method' object is not subscriptable
```
Here, `len` is a built-in function in Python that returns the length of an object, such as a string, list, or tuple. However, it is not subscriptable, so you cannot use square brackets to access its elements.
To fix this error, make sure that you are using square brackets only with objects that support indexing, such as lists, tuples, and strings. If you are unsure whether an object is subscriptable, you can check its type using the `type()` function.
TypeError: 'builtin_function_or_method' object is not subscriptable
这个错误通常出现在你试图对一个函数或方法进行下标操作时。请检查你的代码,看看是否有类似于以下的操作:
```
my_function[0]
```
这是不正确的,因为函数或方法是不支持下标操作的。如果你需要获取函数或方法的某个返回值或属性,请直接调用该函数或方法并将其结果存储在变量中,然后使用该变量来进行后续操作。
