Help - Codershadow - Mar-20-2017
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()

I am new to python but i guess the below code should help
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)]
j = 0 #Changes were made here
j = j + 1 #Changes were made here
for i in range(0,gridSize):
grids[i-1]=[j for j in range(gridSize)] #Changes were made here
return grids
def grid_def():
for i in range (0,gridSize):
print (grids[i-1])
grids = gridSize_def()
grid_def()

If you don't want them all set to 0, stop setting them all to 0 :p
