adventofcode2016

My solutions for adventofcode.com (2016) with Python.

My base classes

Solution

  • Solution for a day can calculate part 1 and 2
  • Input is loaded from file input.txt inside the folder of the day
  • Solutions of a day have to define their own calculate method

Test

  • Sets up and tears down calculation of a solution for a day
  • Mocks the input from the input.txt by an input string

My modules

Point2D

  • 2D point inside cartesian coordinate system
  • Set and get x and y coordinates
  • Add, sub and neg points
  • Calc euclidean and manhattan distances between points
  • Print point coordinates

Map

  • Map based on Image class (Pillow)
  • Set and get values for 2D points
  • Get minimum and maximum coordinates of set points
  • Show map image
  • Image output gets flipped depend on coordinate origin

Keypad

  • Standard is 9-button keypad
  • Load custom keypad from JSON file
  • Move finger in direction
  • Press button and append code

Triangle

  • Set and get side lengths
  • Check if triangle is possible

Dict

  • Sortable dictionary
  • Get sorted strings with arbitrary length
