The Next stage Going forward, we will focus on answering questions about a larger set of stock data, foundational questions such as the variance of closing prices to the more complex questions such as if the stock price of IBM and of MSFT are similar.
For example, IPython has a figsize function via pylab, which allows you to set the size of the plot. Reporting with pandas objects (Medium) In the final recipe, we'll do an example that is a bit more complex than the one in the recipe in which we introduced Flask as a backend. Flask can often be used for dead simple APIs, so in this recipe we'll walk through filtering a DataFrame by month via a Flask route. While the data will be fed to a template, this recipe can easily be modified to jsonify the DataFrame and do something with an API.
