Typing

• To do a type annotation for items in a list (a vector basically) you can pass the type like list[int] but this can also be used to pass things like a list of int lists: list[list[int]]
• But now in newer versions of python you can just use the built in types
  • To use List as a type you need to from typing import List : List[List[int]]
  • Dictionary typing: x: Dict[str, str] = {"a": "b"}
    • from typing import Dict
  • Set typing: x: Set[str] = {"a", "b"}
    • from typing import Set
  • Now all of these are available as set dict list
