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

Please help!!!

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

The program is an illustration of the random module

The program in python, where comments are used to explain each line is as follows:

#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()
