100 Days of Python, Project 083 – Tic-Tac-Toe #100DaysofCode

December 12, 2022

Writing this write up took considerably longer than actually writing the code.

I saw a post once commenting how the world doesn’t need another version of Tic-Tac-Toe made in Python. Well that’s too bad, because here comes another one! I keep telling myself I want to make a slightly more detailed run through some of my code writing, just for the sake of “This is the process,” so let’s see if I can make a go of it for this round. Funny enough, this isn’t the first time I’ve set out to make TicTacToe on my own accord, I once started working out doing it in C++ once, mostly because I wanted to see if I could build a super tough algorithm for a computer AI playing TicTacToe.

This whole post will contain a whole lot of somewhat repetitious and incremental Python code, but maybe it will be helpful to some newbie coders to get a better idea of how to step through what you’re writing and how to break up and plan different parts of your code.

The first step here, is to decide which method to use to create this little game. I could do it with Text but that feels ugly and boring. I could probably make a web version with Flask, but that feels overly complicated. That leaves Tkinter or Turtle. I opted for Turtle. I like Turtle, it has a fun sort of retro feel to it, and it’s simple enough to use.

This post is Extremely Long and full of code, so I’m putting ti behind a Read More, and here it is!

100 Days of Python, Project 081 – Morse Code Generator #100DaysofCode

November 27, 2022

I feel like these last 19 projects are more complex and should get their own post each.  Just skimming over what they are, they all seem to be quite a bit more complex than a lot of the previous projects, and they also are given no help or instruction, just “Make X”.

I wanted to comment a bit briefly on the course as a whole so far though.  I’ve really enjoyed it, and I have lots of idea of projects I WANT to do, and I have started on a few, but I’m doing my best to force myself to focus on finishing this course FIRST.  Eyes on the Prize, so to speak.  The flow overall is pretty good, though I noticed some of the course comments, many people were complaining a bit during some parts.  Mostly about the lack of videos during the final, third or so, of the course.  I admit, I kind of feel for them a bit, but I also do somewhat get the point.

The point is, at some point, you do need to do this stuff without everything being hand-holdey the whole way.

That said, she was doing a pretty good job of this already within each “Broader” topic.  For say, Turtle Graphics, she would start off being extremely “Do X, Do Y, Do Z” about pretty much every step of a project.  Next lesson, there would be a bit less, then by the third it would ask the students to do something, then give a solution.  Eventually it was just, “Do a while project” with “here is a solution”.  It was gradual over 5-6 lessons.  

It feels like she tried to do this quite a bit with the overall course as well, the problem is, when you end up in an area that is completely unfamiliar again, like the Flask sections, or the Data Analytics sections, it would be a bit nice to start each “New Section” with some videos and a bit more help.

Personally, I didn’t find it too much of a problem, I was already doing many of the projects without watching any of the videos, then watching videos afterwards to see how she did it.  The user comments also were really great for suggestions and ideas.

I would still recommend the course.  It seems to be one of Udemy’s best selling courses too.

Anyway, on with the project, and I admit, I am kind of adding some filler.

Day 81 – Morse Code Translator

Ok, so, compared to what the rest of the “Professional” level projects seem to be, this particular project felt stupid super easy.  Like, “am I doing something wrong” easy.  I may have even already done this one evening on CodeWars.com.  I even fleshed it out a bit just to make it more interesting.

The project was to translate a user input into Morse Code.

Even just thinking about that, at it’s core, it’s literally just find and replace on a string.

Step One – Create a Dictionary of Morse Code sequences and the equivalent Alphabet letters

Step Two – Get a User Input

Step Three – Loop through the Input and convert each character using the Dictionary to Morse Code

That is IT.  That’s nothing.  The assignment also specified “Text Based”, though I considered converting it to work in TKinter or maybe even Flask.

I did spruce things up a bit, I added a prompt so the user can translate additional strings.  I looked up how to make sound output, and added an option to play the Morse Code out over the PC Speaker, which was fun, and new useful information.

Anyway, it’s on Github, but this is the entire code.

            # Needs a brief pause
            sleep(.05)

100 Days of Python, Projects 71-80 (but not really) #100DaysofCode

November 21, 2022
Python Logo

Ok, I’m going to be frank here.

I’m skipping most of the Data Analytics portion of this course.  It’s 9 Lessons, Day 71-80.  It is all done using Google Colab Notebooks, it’s all extremely, extremely, extremely, repetitive, yet I am not really feeling like I am learning anything.

Every lesson amounts to, Open this Google Collab Notebook, which is a new and… interesting tool, I guess it’s similar to a Jupyter Notebook.  It’s basically, running “code” in weird choppy step by step chunks.  Each lesson amounts to.

  • Open a provided CSV file.
  • Make a Graph
  • Format the Graph.
  • Maybe do some layered graphs.
  • Sometimes the type of graph is different (line, bar, scatter, etc).

It’s dull, it’s repetitive, I have almost zero interest in statistics and data science honestly.  Fun Fact, Statistics is the one class I dropped in college.  I could have gotten a minor in Math with my Mechanical Engineering Degree with one more math credit, so I took Statistics.  It was the only class I had any actual homework in my last semester, everything else was writing reports, the homework was absolutely brutal, and the entire class felt like butchering math to create Conformation Bias.  It was stupid, it doesn’t account for nuance and one offs, which is what you should actually care about because those are the failure points.  I could go on and on.

Anyway, the sections tarted out pretty fun, learning  new tool, making fancy graphs, then halfway through I found I was just copying and pasting answers from the lecture because I just wanted it to be over and I didn’t care about the material.  

So I’m just, skipping it. This isn’t a graded University Course, hell I have made plenty of small side projects during this course to fill in the idea of “100 Projects in 100 Days”.

Also, if I wanted to make pretty charts, I would just use Microsoft Excel.  Because I am already pretty good at that.

This leads into the final “stretch” of this course, which I have already started working on some.  The Final 19 Projects, which are all basically, open ended suggestions.  There is a Data Analytics one in there, which I actually probably will go ahead and throw together some Charts for.  I have the perfect Data Set for it, ever since I bought my car, back in 2015, I’ve tracked my mileage and fuel usage every time I fill up (in Excel).  I can dump out a huge CSV was and manipulate that data in Google Collab or a Jupyter Notebook.
