Answer:
import random
def grid_maker(x, y):
return [ [str(random.randint(-30, 30)) for _ in range(x)]for _ in range(y) ]
print ('\n'.join(' '.join(row) for row in grid_maker(4, 5)))
Explanation:
We use a template function and we generate numbers between -30 and 30:
>>> [str(random.randint(-30, 30))]
We also use the str() method so we can later concatenate the integers with \n. If you do not specify the integers, it will cause a crash. Also, keep in mind if we use a variable to store the integers, it will come out more of like a seed than a random grid. For instance, output without the random integers in a variable:
-12 16 -18 -3
7 5 7 10
18 -21 -16 29
21 3 -4 10
12 9 6 -9
Vs with a variable:
-25 6 -25 -20
-25 6 -25 -20
-25 6 -25 -20
-25 6 -25 -20
-25 6 -25 -20
Next we specify the x and the y:
>>> for _ in range(x)]for _ in range(y) ]
Next we just print it and create a new line every time a row is made
hope this helped :D
