I am new to coding and data science as well. I found it useful to find my own original dataset as it also practices the skill of finding and cleaning dataset. I've seen courses recommend to do this as well.

One dataset I created myself was I extracted the metadata from every photo on my computer, e.g. resolution, size and date taken. I then plotted all the data on a graph and tried to determine which camera of mine had taken the picture, from the data.
