Programing Python 2D Array

Question

Write a program that creates a 4 x 5 array called numbers. The elements in your array should all be random numbers between -30 and 30, inclusive. Then, print the array as a grid.

For instance, the 2 x 2 array [[1,2],[3,4]] as a grid could be printed as:

1 2

3 4

Answer 1

#This imports the random module

import random

#This is repeated four times (the rows)

for i in range(4):

#This is repeated five times (the columns)

for j in range(5):

#This prints a random number between -30 and 30

print(random.randint(-30, 30),end = ' ')

#This prints a new line

print()
