ype' object is not subscriptable

This error message typically occurs in Python when you try to use square brackets to access an element of an object that does not support indexing.

For example, if you have a variable of type `int`, you cannot use square brackets to access individual digits of the number. Similarly, if you have a string variable, you can use indexing to access individual characters, but you cannot use it on the string itself.

Here's an example of how this error might occur:

my_string = "hello"
x = my_string[0]
y = x[1]

In this example, `my_string` is a string variable and we can use indexing to access its individual characters. However, in the second line, we are trying to access the second character of `x`, which is an `str` object. Since `str` objects do not support indexing, we get a `TypeError: 'str' object is not subscriptable` error.
