Today's Progress: Studied python built in functions. Started a project on Detecting Youtube Comment Spam using bags of words and random forest. Had an issue with i am still trying to resolve.
Thoughts: Since I am currently learning python alongside machine learning, I have decided to complete a project at least once in two days to speed up my progress.
