Why does Python throw an unhashable type: 'dict' error?

Question

Python

Python throws an error unhashable type: 'dict'.
Here is the code that is causing the problem:

def delete_product(user_group, shop = shop, **products):
    if user_group in shop:
        shop[user_group].pop(products)

Answer 1

You are trying to use a non-hashable type as a key in the dictionary (in this case, judging by the error, the user_group dictionary is also).
A dictionary key can only be a hashable type, such as a tuple (no nested non-hashable elements), a string, a number, and so on.
