Write a function that reads a single line of numbers from a file named
"question1.txt", and returns the average of the numbers read. For example, if
the file is as follows:
----- question1.txt -----
1 3 5 -2 4 0 6 -2 -3
-------------------------
then the function must return 12/9 = 1.33333

Write a function that reads a single line of numbers from a file named "question1.txt", and returns the average of the numbers read. For example, if the file is as follows:
----- question1.txt -----1 3 5 -2 4 0 6 -2 -3-------------------------
then the function must return 12/9 = 1.33333
(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. 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.

- At the end of this and other textbooks, there usually is an index that lists the pages where a certain word appears. In this problem, you will create an index for a text but, instead of page number, you will use the line numbers. You will implement function index() that takes as input the name of a text file and a list of words. For every word in the list, your function will find the lines in the text file where the word occurs and print the corresponding line numbers (where the numbering starts at 1). You should open and read the file only once Create the python function as part of a python program.
