That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.

- Write a function in python named "read_words" that declares a parameter for a filename and returns a collection of unique words in the file. Even though words.txt contains a single word per line, you should not assume that this is true of every file. For example, if the line is a sentence, you should split the line into individual words before storing each word in your collection. Handle any errors that occur by printing a detailed error message.
