"""Mutable datatypes such as lists or dictionaries have variables that **reference** the list or dictionary they do not actual store the list or dictionary as opposed to an immutable datatype(string, int,...) which variables store the actual **value**.""" spam = [0, 1, 2, 3, 4, 5] cheese = spam cheese[1] = 'Hello!' #NT: Both variables are changed because both **reference** the same list. print(spam) # prints [0, 'Hello!', 2, 3, 4, 5] print(cheese) #prints [0, 'Hello!', 2, 3, 4, 5]
