How can I print a one dimensional array as grid in Python?

I have an array of 200 items.

grid = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 .... and so on]

How can I print it as a 2D array like so? Split it every 10 characters actually.

0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,

I have tried things such as

def Print(grid):
    for i in grid:
        if(len(i) % WIDTH-1 == 0):
            print(i)
        else:
            print(i, end = ' ')

with no success.

You can iterate of the length of grid, in this case 200 by 10 and use that as the start for your slicing, printing that plus 9 additional values.

grid = [0]*200
for x in range(0,len(grid),10):
    print(grid[x:x+9])

edit: This will print slices of the list, which is still a list which is why you see the brackets. Like others have shown you can use join and map to print it as a comma separated string if you really need to:

grid = [0]*200
for x in range(0,len(grid),10):
    print(','.join(map(str,grid[x:x+9])))

Output

[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
[0, 0, 0, 0, 0, 0, 0, 0, 0]
