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

Triangle

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

Dict

• Sortable dictionary
• Get sorted strings with arbitrary length
