Being a novice at data science, I am always on the lookout for new free courses and datasets to experiment on in an effort to improve on my existing skillbase. One such dataset that I found was Kaggle’s heart attack dataset, the link being here:- Heart Attack Analysis & Prediction Dataset | Kaggle

I decided to use the dataset even though it seemed quite similar to the heart disease dataset that I had previously experimented on. As I conducted an analysis for the heart attack, I realised that the analysis for the heart attack dataset was the same as the…

In recent months I have been writing posts about the Coronavirus pandemic because it is one topic that is on everybody’s minds. Being in lock down has been a very huge inconvenience on people, but it has been necessary to save lives. There are many people who complain about having to be in lockdown, saying the people who the virus mainly affects are the elderly and individuals with weakened immune systems. I have found out through both professional and personal channels that this simply is not true. I think, therefore, it is a good time to revisit the Coronovirus with…

After having learned some elementary Python code, I decided to dig deeper into the programming language. I have therefore recently studied error handling, which is code that prevents and/or corrects faulty input. The link to my previous post on error handling in Python is here:- An initial example of Input Error Handling in Python | by Tracyrenee | CodeX | Jun 2021 | Medium

In this post, I am going to discuss the ZeroDivisionError in Python, which arises whenever someone tries to divide a number by zero. In mathematics, when a number is divided by zero, the result is infinity…

As I have progressed in my studies of Python programming, I have begun to study error handling, which is important to ensure the robustness of a script. One type of error is an input error, which is an error that the user makes when he is inputting data.

I have included the code for a short script I have recently written. The script below is a very small program that will be able to tell the user whether an entered number is odd or even.

The user is prompted to enter a number and this number is converted from a…

In the paste I had been using on-line screen recorders to record the videos that I put on YouTube. I particularly liked the on-line screen recorders that allowed me to put my picture at the bottom of the screen so my viewers could see who I was.

Yesterday I went to use the on-line screen recorder that I normally use and for some reason there was a bug in the vsoftware, which meant that I was unable to download the recording onto my computer. …

In my last post I discussed how I achieved a score of 1.999 in my first attempt at Kaggle’s June 2021 tabular competition by using sklearn’s BayesianRidge() in my first attempt at the competition. The link to my most recent post on this subject can be found here:- A data scientists first attempt at Kaggle’s June 2021 tabular competition | by Tracyrenee | MLearning.ai | Jun, 2021 | Medium

After I completed the post, I experimented with some other estimators and was able to improve my score and achieve a rating of 1.76212 by using sklearn’s HistGradientBoostingRegressor(). In this post…

For those individuals who follow the Kaggle competitions, they are having a tabular competition every month for the year 2021, so I decided that is something that I should be able to do while I am still studying Python. Last month I won a bronze medal on the May 2021 Kaggle tabular competition, and the link to the post I wrote on the subject can be found here:- https://medium.com/codex/how-i-won-a-bronze-medal-on-a-kaggle-competition-4abd0424c479

The June 2021 competition question is similar to the May 2021 tabular competition, so the same methodology that I used to solve that competition question can be used to solve this…

I have been studying Python for a year now in an attempt to learn data science and other methodologies in this field. I had learned the inbuilt print() function early on in my studies, as the first program that any Python student makes is to print the words “Hello World” onto the screen. One thing that I was not very sure about, however, was the format() function, so I refrained from using it.

In order to enhance my skills, I have been endeavoring to take free online courses. In one such lesson that I had taken, I was required to…
