Data Structures

Data Structures

1. Lists

   • Declaration: thisList = [ ]
     • Elements in a list can be Ints, String, Tuple, Boolean or Another List
       • Accessing: thisList | Accessing Element: thisList[ _ ]
         • List is Ordered
           • Lists are Mutable (Can Make Changes)
             • Adding Elements: thisList.append( _ )
               • Removing Elements: thisList.pop()

2. Tuples

   • Declaration: thisTuple = ( )
     • Data Types in Tuple can be Ints, Strings, or Booleans
       • Accessing: thisTuple | Accessing Element: thisTuple[ _ ]
         • Tuple is Ordered
           • Tuple is Immutable (Cannot be Updated / Add Elements)

3. Sets

   • Declaration: thisSet = { }
     • Data Types in Sets can be Ints, Strings and Boolean, but CAN'T be Repeated
       • Accessing: thisSet
         • Sets are Unordered -> Cannot Access Specific Element
           • Sets are Mutable
             • Adding Elements: thisSet.add( _ )
               • Removing Elements: thisSet.remove( _ )

4. Dictionaries

   • Declaration: thisDict{ "key" : value }
     • Data Types in Dictionaries can be Ints, Strings, Boolean and List
       • Accessing: thisDict | Accessing Element thisDict["key]
         • Dictionaries are Ordered
           • Dictionaries are Mutable, but Keys cannot be Duplicated
             • Adding Elements: thisDict["key"] = value
               • Removing Elements: del thisDict["key"]
