Linear Data Structures

Linear Data Structures

1. Lists

   • ordered
   • changeable
   • allows duplicates
   • elements with different data types
   • ex: list = ["dog",True,4]

2. Tuples

   • ordered
   • unchangeable
   • allows duplicates
   • ex: tuple = ("cat",31,False)
   • elements with different data types

3. Sets

   • unordered
   • unchangeable
     • but you can add elements a set or merge 2 sets
   • no duplicates
   • can check if an element exists in the set
   • ex: set = {"puppy",True,4}
   • elements with different data types

4. Dictionaries

   • stores data in key:value format
   • like maps in C++
   • changeable
   • ex: dictionary = { "name": "Miranda", "year": "sophomore"}
