Hi, I'm trying to create a 3D grid, so I'm using a list of list of lists. However, if I try to make a change to one value, eggrid[0][1][2] = 3, It doesn't just change list[0], it change the 2nd element in the 1st list of every list? I think it's because I've copied lists to get the grid, but could you help me fix this? This is my code, that takes an x,y,z value from user. self.grid_x = xself.grid_y = yself.grid_z = z self.grid = []self.grid2D = [] for i in range(self.grid_y): row = [0]*x self.grid2D.append(row) for k in range(z): self.grid.append(self.grid2D) #Creates list of x by y grids Thank you so muchCorrine
