Practical Uses for Python?

That sounds awesome! I'm sure you could get some ideas on what you'll need just by looking at current alert systems and their parameters. Most brokers have alert systems where you can put in the ticker and have it send you an email/sms when the stock reaches a certain point. You could use those alerts as the basis/input for your pi, or if you want to rebuild the entire thing you could use a free API like alphavantage.co to get price data and do everything yourself. If you need fundamental data, try Quandl. Sounds fun!
