Getting the last n elements of a list in Python. You can use the slicing operator[-N:], where N is the number of elements you want to retrieve from the end of the list. You can get the last n elements of a list in Python using many ways like, list slicing, loop, islice() + ...
You can remove the last element from the tuple using positive indexing. Create a tuple namedmytuplethat contains the elements ("Python","Spark","Hadoop","Pandas"). By using the slice notation[:len(mytuple)-1], a new tuple result is created that excludes the last element. The resulting ...
In this tutorial, you will learn how to interchange the first and the last elements in a list in Python. Lists in Python are a group of ordered values that are closed within a square[] bracket. For a given list, we have to write a Python program that will swap the first and the...

Alternatively, if you desire the final elements present in every row. with open('data.csv', 'r') as csv: data = [line.strip().split(',')[-1] for line in csv.readlines()] print(data) Solution 2: After obtaining the final row, it is now possible to divide it into a list. For...
Write a Python program to exchange the first and last characters of a string using slicing. Write a Python program to convert the string to a list, swap the first and last elements, and then join it back into a string. Write a Python program to implement this swap recursively by handling...
