This is the most popular way by which the duplicates are removed from the list is set () method. But the main and notable drawback of this approach is that the ordering of the element is lost in this particular method. Python3. test_list = [1, 5, 3, 6, 3, 5, 6, 1] print ("The original list is : ". Removes all the elements from the list. copy () Returns a copy of the list. count () Returns the number of elements with the specified value. extend () Add the elements of a list (or any iterable), to the end of the current list. index () Returns the index of the first element with the specified value.

Python3. Approach #3: Swap the first and last element is using tuple variable. Store the first and last element as a pair in a tuple variable, say get, and unpack those elements with first and last element in that list. Now, the First and last values in that list are swapped.This code creates a list of fruits, then accesses and prints the first entry ("apple") from the list, followed by accessing and printing the second element ("banana"). Output apple banana. Read More - Python Developer Salary in India. Update List in Python. Updating a list in Python is essential to developing programs and applications.
