PENTOMINOES
Some Pentomino Utilities

PENTOMINOES is a Python library which provides some utilities for manipulating pentominoes.

A pentomino is a shape formed by connecting 5 unit squares edgewise. Ignoring reflection and rotation, there are 12 distince pentominoes, nicknamed F, I, L, N, P, T, U, V, W, X, Y and Z.

Source Code:

• cell_ij_fill.py fills a unit square with a color.
• pentomino_display.py displays a particular pentomino in a 5x5 grid.
• pentomino_matrix.py returns a 0/1 matrix defining a particular pentomino.
• timestamp.py prints the YMDHMS date as a timestamp.

Examples and Tests:

• pentominoes_test.py
• pentominoes_test.txt

One of the test codes generates plots of each pentomino:
