Python/Types

• Indicate the type of a variable, is optional.
• Benefits, is warnings from editors if used wrong, or passing wrong type.

• Use pydantic to validate incoming data, by creating a basemodel class.

  # e.g.
  from pydantic import BaseModel
  
  
  class User(BaseModel):
      id: int
      name = "John Doe"
      signup_ts: Optional[datetime] = None
      friends: List[int] = []

• Python/FastApi also uses pydantic + types to auto validate incoming data when building an api.
