TypeError: object is not subscriptable

$TypeError: 'NoneType' object is not subscriptable

Analysis

You are trying to access an item using square brackets [] (like a list or dict) on an object that doesn't support it (like None, int, or float).

Common Triggers

●A function returned None instead of a list/dict.
●Confusing a single object with a list of objects.

Debug Checks

$Print the type of the variable: print(type(var)).
$Check if the variable is None.

Resolution

Ensure the variable is a list, tuple, or dictionary.

Handle the None case before accessing with [].
