Dict is the name of a built-in type within Python you are noticing what appears to be a novel error message, although, in actuality, this is not. The type of dict is a type. Therefore you are attempting to index within the type object. That is why the error message states that the 'type object is not subscriptable.'

Hey Tom,

The TypeError: Nonetype object is not subscriptable is an error that occurs when you try to subscript an object that has a none value.

For example:

Here I have given a none value.

Traceback (recent employee list)

File subscriptable.py, line 2, in <module>

temp=list1[0]

TypeError: ‘NoneType’ object is not subscriptable

To fix this error, use the code below.

list1 = [1,2]

list1.sort()

temp = list1[0]

print(temp)

Usually, this TypeError occurs because when the user code indicates an attempted operation on an object is not supported, and is not meant to be used. Passing an argument of the wrong type may result in a TypeError.
