Now let’s implement the rules of the game of life! a given configuration of the grid in the game of life is known as a generation of cells. write a function next_gen(grid) that takes a 2-d list called grid that represents the current generation of cells, and that uses the rules of the game of life (see above) to create and return a new 2-d list representing the next generation of cells. notes/hints: begin by creating a copy of grid (call it new_grid). use one of the functions that you wrote for the previous problem! limit your loops so that they never consider the outer boundary of cells. you did this already in one of the functions that you wrote for the previous problem. you can use the count_neighbors() function that you just wrote. make sure that you count the neighbors in the current generation (grid) and not the new one (new_grid). when updating a cell, make sure to change the appropriate element of new_grid and not the element of grid.
