Key Points

  • Use [value1, value2, value3, ...] creates a list.
  • Lists can contain any Python object, including lists (i.e., list of lists).
  • Lists are indexed and sliced with square brackets (e.g., list[0] and list[2:9]), in the same way as strings and arrays.
  • Lists are mutable (i.e., their values can be changed in place).
  • Strings are immutable (i.e., the characters in them cannot be changed).
