Screen Buffer Using 2D Array - Python Programming Exercise

import random

# Define the dimensions of the array
rows = 20
cols = 70

# Create a 70x20 two-dimensional array initialized with spaces
array = [[' ' for _ in range(cols)] for _ in range(rows)]

# Draw 80 'X' characters in random positions
for _ in range(80):
    row = random.randint(0, rows - 1)
    col = random.randint(0, cols - 1)
    array[row][col] = 'X'

# Display the content of the array
for row in array:
    print(''.join(row))
