List method to delete last element in list as well as all elements

Question

I have an issue with clearing lists  In the current program  I have a method that clears a certain number of lists  This is rather inconvenient since during one part of the program where this method is used  it would be a lot more helpful if it only deleted the last element from the lists  Is there any way in which I can set index numbers as parameters to my method to solve this problem    The code for the method  def clearLists self       del self Ans        del self masses      Whenever I want to use this method  I merely write self ClearLists   and it deletes every element in a list
