Lecture Notes on 25 Sep 2013

* We covered 
    - arithmetic operators: + - * / // % **
    - built-in functions

* Today we will discuss:
    - comparison operators: < <= > >= == !=
    - boolean operators: not, and, or
    - bitwise operators: ~ & | ^
    - shift operators: << (multiply by 2 ** n)
                       >> (divide by 2 ** n)

* Outline of EasterSunday.py

def main():
  # Prompt the user to enter the year
  y = int (input ('Enter year: '))
  print (y)

  # Apply algorithm by Gauss
  a = y % 19
  print (a)

  b = y // 100
  print (b)

  c = y % 100
  print (c)

  ...
  
  # Write out the result
  if (n == 3):
    print ('In', y, 'Easter Sunday is on', p, 'March')

  if (n == 4):
    print ('In', y, 'Easter Sunday is on', p, 'April')
