      Add Array Items

      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      Add Array Items

      The append() Method

      The append() method adds a new element at the end of given array.

      Syntax

      array.append(v)

      Parameters

      • v − new value is added at the end of the array. The new value must be of the same type as datatype argument used while declaring array object.

      Example

      import array as arr
      a = arr.array('i', [1, 2, 3])
      a.append(10)
      print (a)
      It will produce the following output 
      array('i', [1, 2, 3, 10])

      The insert() Method

      The array class also defines insert() method. It is possible to insert a new element at the specified index.

      Syntax

      array.insert(i, v)

      Parameters

      • i − The index at which new value is to be inserted.
      • v − The value to be inserted. Must be of the arraytype.

      Example

      import array as arr
      a = arr.array('i', [1, 2, 3])
      a.insert(1,20)
      print (a)
      It will produce the following output
      array('i', [1, 20, 2, 3])

      The extend() Method

      The extend() method in array class appends all the elements from another array of same typecode.

      Syntax

      array.extend(x)

      Parameters

      • x − Object of array.array class

      Example

      import array as arr
      a = arr.array('i', [1, 2, 3, 4, 5])
      b = arr.array('i', [6,7,8,9,10])
      a.extend(b)
      print (a)
      It will produce the following output 
      array('i', [1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
