Another better way to do this is to add a check to make sure the object is not None before we try to access it. my_list = None if my_list is not None: print (my_list[0]) 2. Not checking for NoneType objects. In some cases, you may receive a NoneType object from a function or a method. If you then try to access an index or key of that object ...
[Solved] TypeError: 'NoneType' Object is Not Subscriptable
Resolving the 'NoneType' object is not subscriptable.

This is the line that's causing the error, at any rate. dict is a type. You have to create a dictionary before you set keys on it, you can't just set keys on the type's class. Don't use "dict" as var_name. Then you can use it.
Built-in Exceptions
CPython implementation detail: Most built-in exceptions are implemented in C for efficiency, see: Objects/exceptions.c.Some have custom memory layouts which makes it impossible to create a subclass that inherits from multiple exception types.
