I'm always up for building a good program that incorporates lots of good Python modules.
Prior to this, I have built a Twitter Tweet-Bot that uses the Twitter API to stream tweets and ultimately generate a WordCloud that represents the phrases used often by a particular user.
Another project I have done quite recently is, a ChatBot. Using the NLTK library I was able to program a Bot that answers questions regarding a particular topic it has been trained in. This was done using algorithms like data lemmatization and TFIDF Vectorization.
I look forward to creating more advanced and interesting programs in the near future!
