I've written this to get a grid in python and I want to know how to change the numbers in the grid to go up like 1,2,3,4 etc... instead of all being 0
def gridSize_def(): global gridSize while True: try: gridSize = int(input("input grid length and width\n")) if gridSize<2: print ("invalid int") else: break except ValueError: print ("invalid input") grids = [[] for _ in range (gridSize)] for i in range(0,gridSize): grids[i-1]=[0 for _ in range(gridSize)] return grids def grid_def(): for i in range (0,gridSize): print (grids[i-1]) grids = gridSize_def() grid_def()
