The universe of the Game of Life is an infinite, two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, live or dead (or populated and unpopulated, respectively).Every cell interacts with its eight neighbours, which are the cells that are horizontally, vertically, or diagonally adjacent.At each step in time, the following transitions occur: Each cell in the grid can be in one of two states: alive or dead. Why do academics stay as adjuncts for years rather than move around? Almighty T-Shirts "Say it on a T-shirt" After my divorce I am not looking for a serious relationship. Not the answer you're looking for? You're running out of memory because calculatingcoords never becomes False , and the loop runs forever, appending more and more items to coordi To visualize the two-dimensional case, we can think about a person in the imagination who is walking randomly around a city. Notation: The simplest grid (with the fewest resistors) is shown below this paragraph. In this section we will explore how iteration allows us to manipulate these images. This means that it generally doesn't take longer to access or store data in lists or dictionaries as they fill up with data. By using lazy evaluation.
