In pyton: In this lab, you will be building a software application that removes duplicate values from a list.The purpose of the assignment isto gain experience with user-defined functions, forloop and listmanipulation. Start  Start of remove duplicate function (numbers: list of numbers)     Initialize an empty list as new_list     Loop over each of the number of the numbers list         If number not in new_list              Append number to new_list     Return new_list End of remove duplicate functionStart main function     Prompt user for list of numbers     Call remove duplicate function     Print the new list returned by the remove function End of main functionEnd

With Head node or not? statement is: if(first->llink == first) output << "List is empty"; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.
