[Help] List of Lists not printing both Cmder/Anaconda?

[vanicci]

Hi Python mentors,

I tried running this code:

import random

M = 'land'
o = 'water'
h = 11 #number of rows
w = 11 #number of columns
matrix = []
world = [
         [o,o,o,o,o,o,o,o,o,o,o],
         [o,o,o,o,M,M,o,o,o,o,o],
         [o,o,o,o,o,o,o,o,M,M,o],
         [o,o,o,M,o,o,o,o,o,M,o],
         [o,o,o,M,o,M,M,o,o,o,o],
         [o,o,o,o,M,M,M,M,o,o,o],
         [o,o,o,M,M,M,M,M,M,M,o],
         [o,o,o,M,M,o,M,M,M,o,o],
         [o,o,o,o,o,o,M,M,o,o,o],
         [o,M,o,o,o,M,o,o,o,o,o],
         [o,o,o,o,o,o,o,o,o,o,o]
        ]

def gen_maze():
    rows = []
    for i in range(w):
        matrix.append([])
        col = []
        for j in range(h):
            # matrix[-1].append(0)
            value = random.choice(['o', 'M'])
            col.append(value)
        rows.append(col)
    return rows

gen_maze()

but it wouldn't run either Cmder or Anaconda Prompt?

It works okay in Jupyter though. Is it because the file ends in .ipynb?

Do you have any idea what's causing this?

Thank you.
