It's time to practice your focus and memory! For this discussion, you are going to watch a video that has a memory and attention game. It is important that you understand the instructions.  The memory game is going to test your memory of the alphabet and your attention. If you do not understand the instructions, then pause and replay the video before going on with the game. If you need to write out the alphabet and have that in front of you, then you can also do that.  Watch the Nat Geo Maintain Your Focus (Links to an external site.) video and play along.  Be sure to write down your results!  In the discussion, share what you learned about your memory. Start your discussion post by sharing how you performed. Did you get most of the words right or not? Did you notice other details or did you miss them? What did you learn about your memory from this experience?  To receive full credit, remember to also write three posts in the discussion: one original and two responses to other students. Provide scholarly, cited responses where applicable. Do not use Wikipedia. Use the library or reputable source to support your posts.! Please use the webtext or a credible and scholarly source to: 1. Share your results 2. Define memory 3. Identify and describe the difference between long-term and short-term memory 4. Share how it applies to your future career link to the site talked about above if it isn't working:  https://www.kaltura.com/index.php/extwidget/preview/partner_id/956951/uiconf_id/39456672/entry_id/1_e22f7tfe/embed/iframe?

Write a function (call it get_fh) that receives two arguments: 1). A file name 2). How to open a file for reading or writing ("r", or "w") in Python. The purpose of this function is to open the file name passed in, and pass back the file handle. I can call this function like this: fh_in = get_fh(file_2_open, "r") or fh_out = get_fh(file_2_write, "w") **When using open(), make sure to use try .. except .. except if the open was not successfu the program should raise the right Excpetion(it should raise an IOError for when the file cannot be opened, and raise a ValueError when the wrong argument was passed for the opening mode, e.g. "rrr" instead of "r"). We will test for things like a file that does not exist for opening, or the wrong open mode, e.g. mode='rrr'. See open for more information. All opening and closing of files in your program should use the get_fh function.
