#python arrays
#arrays can be defined in the following
# class array.array(typecode[, initializer])
# The typecode character used to create the array eg i for integers , c for strings etch
array = array('i', [1, 2, 3, 100, 4, 4, 5, 20, 20, 20])
#You can perform serveral methods eg remove(),pop()
#removing the last element in the array
array.pop()
#Adding elements to array using the append and insert method
array.append(20)
array.insert(4,100)#adds 100 at index 4
