This error message signifies that you have attempted to perform an indexing operation on an object that lacks the requisite functionality. It is noteworthy that certain methods, such as 'sort()', which solely modify a list, do not yield a printed return value; instead, they return the default 'None.' The error 'NoneType' object is not subscriptable is raised by Python in instances where the square bracket notation 'object[key]' is employed on an object that does not define the 'getitem' method. This underscores a fundamental design principle governing all mutable data structures within the Python programming language.
