Individual elements can be accessed through indexes. Python arrays are zero-indexed. Here is an example : my_array = array('i', [1,2,3,4,5]) print(my_array[1]) # 2 print(my_array[2]) # 3 print(my_array[0]) # 1

my_array = array('i', [1,2,3,4,5]) my_array.append(6) # array('i', [1, 2, 3, 4, 5, 6]) Note that the value 6 was appended to the existing array values.

We can use the insert() method to insert a value at any index of the array. Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.insert(0,0) #array('i', [0, 1, 2, 3, 4, 5]) In the above example, the value 0 was inserted at index 0. Note that the first argument is the index while se...

A python array can be extended with more than one value using extend() method. Here is an example : my_array = array('i', [1,2,3,4,5]) my_extnd_array = array('i', [7,8,9,10]) my_array.extend(my_extnd_array) # array('i', [1, 2, 3, 4, 5, 7, 8, 9, 10]) We see that the array my_array was extended...

Here is an example: my_array = array('i', [1,2,3,4,5]) c=[11,12,13] my_array.fromlist(c) # array('i', [1, 2, 3, 4, 5, 11, 12, 13]) So we see that the values 11,12 and 13 were added from list c to my_array.

Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.remove(4) # array('i', [1, 2, 3, 5]) We see that the element 4 was removed from the array.

pop removes the last element from the array. Here is an example : my_array = array('i', [1,2,3,4,5]) my_array.pop() # array('i', [1, 2, 3, 4]) So we see that the last element (5) was popped out of array.
