Question 1

dictionary

Answer 1

an unordered collection of key-value pairs

Question 2

dot notation

Answer 2

used by modules, dictionaries, lists, and strings. The method is called to the right of the object on which it is applied. Like:
name = “John”
print(name.lower())
john

or todo = {“stuff” : 5 , “things”:6}
todoKeys = list( todo.keys() )
print(todoKeys)

Question 3

mutable

Answer 3

can be altered. lists, dictionaries, and sets all fall into this category. Tuples are immutable. As are strings, integers, and floats. And probably a slew of others which I simply don’t understand at this moment.
