Python Arrays

Arrays are sequence of homogeneous elements

import array

numbers = array.array('i', [1, 2, 3])

numbers.append(4)
print(numbers) # array('i', [1, 2, 3, 4])

# extend() appends iterable to the end of the array
numbers.extend([5, 6, 7])
print(numbers) # array('i', [1, 2, 3, 4, 5, 6, 7])
