In 1970 the British Mathematician John Conway created his "Game of Life" -- a set of rules that mimics the chaotic yet patterned growth of a colony of biological organisms. In a spreadsheet program like Excel, the x coordinates may be represented by letters instead of numbers, but we'll use numbers for both the x and y coordinates. print('Compare the memory usage of a full grid of each of the three approaches:')
A list comprehension would be better 1: def make_board (place): place [:] = [ ["O"] * 5 for _ in range (5)] That replaces everying in place with a bunch of rows of O 's. As I mention below, you shouldn't be using magic numbers. Your physics assignments can be a real challenge, and the due date can be really close feel free to use our assistance and get the desired result. seen.add(id(o))
In my personal view, ease of implementation and debuggability are the most important factors and my use cases don't tend to be at large enough scales where the performance differences are significant. The dictionary only uses up as much memory as it contains data. print(timeit.timeit('read1DList(list1dGrid)', number=10000, globals=globals())) # 8.444686400005594
On this infinite grid of ideal one-ohm resistors, what's the equivalent resistance between the two marked nodes? Everything is much easier and cooler. Python is my programming language of choice. For the first row and first column, if an obstacle is found then start filling 0 till the last index in that particular row or column. The challenge is about navigating a hypothetical memory laid out in a square spiral: You come across an experimental new kind of memory stored on an infinite two-dimensional grid. Question.
