Python Grid

[Noxia]

Hi All,

I am doing a little coding challenge thing for work and I was wondering if anyone knew the answer to this.

I want to display a 12x12 grid which I have done, the issue is that it displays fine on Jupyter but not on Pycharm. I do not know what work are using to mark the code but I wanted to see if this is something I need to change in my code to make it universal or its a pycharm thing. Have to use standard python, no external libraries.

grid_size = 12

# Create a 2-dimensional list filled with square brackets
grid = [["[ ]" for x in range(grid_size)] for y in range(grid_size)]

# Display the grid using ASCII characters
for row in grid:
    print(" ".join(row))

The above displays in Jupyter fine i.e [] 12 across x 12 down

In Pycharm it shows like:
[]
[]
[]
[]

edit: Tried on an online python compiler too and it displayed per Pycharm.

seems to work fine on an online compiler for me, if that is the correct output anyway!

Are they all running the same Python version?

Thank you for that. I have no idea why but it's just suddenly started displaying properly after I put the code inside a function. I really don't understand what has changed!

This is really going to annoy me. It wasn't working on online-python compiler either but I just copied it in again and now it is.

def draw_grid():
    grid_size = 5
     # Initially did this as two for loops but remembered about list comprehensions.
    grid = [["[ ]"] for row in range(grid_size) for col in range(grid_size)]
    for row in grid:
        print("".join(row))


draw_grid()

# This is displaying as one vertical line

def draw_grid():
    grid_size=12
#Createa2-dimensionallistfilledwithsquarebrackets

    grid=[["[]"for x in range(grid_size)]for y in range(grid_size)]

#DisplaythegridusingASCIIcharacters

    for row in grid:

        print("".join(row))

draw_grid()


#This is working correctly.

Edit: Oh I see it, I think it's a scope issue because I use row twice in the first example!
No that isn't it..

OK I figured it out but cannot work out why it displayed as it did, the issue was my comprehension.

grid=[["[]"for x in range(grid_size)]for y in range(grid_size)]

On the incorrect one I added a ']' after the last ", instead of after the first range call. I think this meant I was making a one dimensional list of 12*12.

grid = [["[ ]"] for row in range(grid_size) for col in range(grid_size)]
