Reference link: Array in Python | Array 2 (Introduction and Function)

a=[]

Create an array like [[0,0,0],[0,1,2]]

for i in range(3):

for j in range(4):

for k in range(5):

a1=[i,j,k]

a.append(a1)

Print out in 3 columns

for i in range(1,len(a)):

if i%3!=0:#If you want to print by a few columns, divide by a few

print(a[i-1],end="")

else:

print(a[i-1])

I saw another way to define an array

import array as arr

array_name = array_alias_name.array(type_code, elements)

arr1=arr.array("i",[1,2,3])

for i in range(3):

print(arr1[i])

You can use the Array.insert() and Array.append() methods in Python to add elements to the array.
