Data Structures

1. Tuples

   • ordered, unchangeable, and allow duplicates
     • myTuple = ("","","")
       • Items cannot be changed
         • item = myTuple[x] to access

2. Sets

   • unordered, unchangeable, and reject duplicates
     • mySet = {"","",""}
       • mySet.add to add
         • mySet.pop() removes random mySet.update({}) to merge
           • unordered, so no index

3. Dictionaries

   • stores data in key:value format
     • myDict = {"k":v, "k":v, "k":v}
       • myDict.update({"k":v}) to add
         • myDict.pop("k") to remove
           • myDict["k"] to access

4. Lists

   • ordered, changeable, and allow duplicates
     • myList = ["","",""]
       • myList.append to add
         • myList.remove("") to remove myList.pop(#) to remove index
           • item = myList[x] to access
