Sometimes, while working with records, we can have a problem in which we need to access the initial and last data of a particular record. This kind of problem can have application in many domains. Let’s discuss some ways in which this problem can be solved.
Method #1 : Using Access Brackets
We can perform the possible get of front and rear element in tuple using the access brackets in similar way in which elements can be accessed in list.
# Python3 code to demonstrate working of# Accessing front and rear element of tuple# using access brackets # initialize tupletest_tup = (10, 4, 5, 6, 7) # printing original tupleprint("The original tuple : " + str(test_tup)) # Accessing front and rear element of tuple# using access bracketsres = (test_tup[0], test_tup[-1]) # printing resultprint("The front and rear element of tuple are : " + str(res)) |
The original tuple : (10, 4, 5, 6, 7) The front and rear element of tuple are : (10, 7)
Method #2 : Using itemegetter()
This is yet another way in which this task can be performed. In this, we access the elements using inbuilt function of itemgetter().
# Python3 code to demonstrate working of# Accessing front and rear element of tuple# using itemgetter()from operator import itemgetter # initialize tupletest_tup = (10, 4, 5, 6, 7) # printing original tupleprint("The original tuple : " + str(test_tup)) # Accessing front and rear element of tuple# using itemgetter()res = itemgetter(0, -1)(test_tup) # printing resultprint("The front and rear element of tuple are : " + str(res)) |
The original tuple : (10, 4, 5, 6, 7) The front and rear element of tuple are : (10, 7)
