+this is the etherType text file we are going to use
+there are 43 lines, each one has a hex number, I have to convert
+all those hex numbers into decimal, and then print them back to the text file
+
+NO way I am going to do that by hand. simple, use python!

+we have to convert the EtherType file to this

+the next thing we need to do is to write this to our file, remmember in the actual code we have 'printed' the results,
+in reality we have to save them to python variables to work with them, but it is a good practice to see them first
+and then do the actual programming
+
+you will now notice that we already have the file read in python, so the pointer is now in the last position. We have to
+in a way create a new file with one extra column after the hex number
