      Access Tuple 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.

      Access Tuple Items

      In Python, Tuple is a sequence. Each object in the list is accessible with its index. The index starts from "0". Index or the last item in the tuple is "length-1". To access values in tuples, use the square brackets for slicing along with the index or indices to obtain value available at that index.
      The slice operator fetches one or more items from the tuple.
      obj = tup1(i)

      Example 1

      Put the index inside square brackets to retrieve the item at its position.
      tup1 = ("Rohan", "Physics", 21, 69.75)
      tup2 = (1, 2, 3, 4, 5)
      
      print ("Item at 0th index in tup1tup2: ", tup1[0])
      print ("Item at index 2 in list2: ", tup2[2])
      It will produce the following output
      Item at 0th index in tup1: Rohan
      Item at index 2 in tup2: 3

      Example 2

      Python allows negative index to be used with any sequence type. The "-1" index refers to the last item in the tuple.
      tup1 = ("a", "b", "c", "d")
      tup2 = (25.50, True, -55, 1+2j)
      print ("Item at 0th index in tup1: ", tup1[-1])
      print ("Item at index 2 in tup2: ", tup2[-3])
      It will produce the following output
      Item at 0th index in tup1: d
      Item at index 2 in tup2: True

      Extracting a Subtuple from a Tuple

      The slice operator extracts a subtuple from the original tuple.
      Subtup = tup1[i:j]

      Parameters

      • i − index of the first item in the subtup
      • j − index of the item next to the last in the subtup
      This will return a slice from ith to (j-1)th items from the tup1.

      Example 3

      Take a look at the following example 
      tup1 = ("a", "b", "c", "d")
      tup2 = (25.50, True, -55, 1+2j)
      
      print ("Items from index 1 to 2 in tup1: ", tup1[1:3])
      print ("Items from index 0 to 1 in tup2: ", tup2[0:2])
      It will produce the following output
      Items from index 1 to 2 in tup1: ('b', 'c')
      Items from index 0 to 1 in tup2: (25.5, True)

      Example 4

      While slicing, both operands "i" and "j" are optional. If not used, "i" is 0 and "j" is the last item in the tuple. Negative index can be used in slicing. See the following example
      tup1 = ("a", "b", "c", "d")
      tup2 = (25.50, True, -55, 1+2j)
      tup4 = ("Rohan", "Physics", 21, 69.75)
      tup3 = (1, 2, 3, 4, 5)
      
      print ("Items from index 1 to last in tup1: ", tup1[1:])
      print ("Items from index 0 to 1 in tup2: ", tup2[:2])
      print ("Items from index 2 to last in tup3", tup3[2:-1])
      print ("Items from index 0 to index last in tup4", tup4[:])
      It will produce the following output 
      Items from index 1 to last in tup1: ('b', 'c', 'd')
      Items from index 0 to 1 in tup2: (25.5, True)
      Items from index 2 to last in tup3: (3, 4)
      Items from index 0 to index last in tup4: ('Rohan', 'Physics', 21, 69.75)
