Reflection:

While working on these exercises I noticed I used several concepts we learned earlier in the semester. Concepts such as try/except, if/else statements, and using input from the user. Personally, I found that these exercises helped serve as a refresher for material we have learned thus far in this course while introducing new concepts related to files. There wasn’t anything I found particularly frustrating. I didn’t get my programs to work the way I intended for them to on the first try; however, after a few alterations I managed them to get them working as I had in mind.
