Write the required functions and script that prompts the user for the names of two files: a file representing the marriage preferences of a sequence of men, and a file representing the marriage preferences of a sequence of women; reads these files (storing this information in special data structures: dictionaries storing preference as lists); prints the dictionary/preferences of the men and women in a special form; runs the Gale/Shapley algorithm for finding a stable marriage (tracing its progress, if required); prints the stable marriage as a set of man/woman tuples.

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
