Key Topics to Revise

1. Introduction to Lists

  • Elements of a list are enclosed in square brackets and separated by commas.
  • A list is ordered, so the position of each element matters.
  • A list is mutable, so its contents can be changed after creation.

2. List Operations

  • The concatenation operator + joins two lists.
