In Python, the TypeError unhashable type list occurs when you are providing a list as a key to the dictionary because Python dictionaries only accept hashable data types as their key, and lists aren't hashable.
Because the keys need to be hashable, you can’t use mutable objects as dictionary keys.On the other hand, dictionary values can be of any Python type, whether they’re hashable or not. There are literally no restrictions for values. You can use anything as a value in a Python ...

A Python dictionary key can be nearly any Python object. I say “nearly” because the object in question must be hashable, meaning that it must have a hash value (the output of its __hash__() method) that does not change over its lifetime, and which can be compared to other objects...
Requirement 3 (the values can be anything) fails because sets require their items to behashableso both the keysand valuesin our key-value tuples must be hashable. Side note: I’m not sure why the union operation is even allowed ondict_itemsobjects. What is this good for?
