Printing simple matrix using random module

New easy trick today. Let’s see how to print simple matrix using Python random module.

How to print a matrix?

import random
data = [random.randint(-100, 100) for _ in range(15)]
print((x for x in data if x < 0), end = '\n\n')

for i in range(0, len(data), 3):
    print(*data[i:i+3], sep = '\t')

The script is generating random numbers between -100 and 100. It returns it in 3×5 matrix (3 rows x 5 columns). Numbers are separated by tabs.
