# <h2>Final Remarks</h2>
# <p>This explanation was designed to illustrate how this may be approached. This is not an end-all be-all solution. If this is a repetitive task, you may want to create a directories list and then iterate through that list. In the iteration cycle, execute the commands listed above for repetition.</p>
