The Programs  Implementing 3 programs each in C# and Python  Student Scheduler  Assigns courses and students, sorts according to different criteria  Twenty Questions  A binary tree of QuestionNodes that writes out to and reads from a text file  Towers of Hanoi  Recursively provides a solution to the puzzle

C#  Microsoft’s current language  Compiled  Java-like  Syntax  Logic  An atmosphere of whatever Java got wrong is fixed in C#

Python  Guido van Rossum  Emphasis on readability  Significant differences  Logic  Style  Syntax  Very popular nowadays with amateur developers and some large companies  Google

Comparison  Scope  Methods and Parameters  Types  Compiled vs. Interpreted  I/O  Freedom/Restrictions  Accuracy  Readability
