Python for Finance: Analyze Big Financial Data

The first section shows how to transfer files via FTP and how to access websites via

HTTP.

Web plotting

Web technologies generally allow for better interactivity and for better real-time

support than standard approaches, for example, for plotting data; the second section

introduces the plotting library Bokeh to generate interactive web plots and to realize

real-time plotting of financial data.

Web applications

One of Python’s strengths is its powerful web frameworks to develop web-based

applications; one that is really Pythonic and that has become quite popular recently

is Flask. This chapter illustrates techniques for developing web-based applications

using this framework.

Web services

Web services have become an important aspect of web-enabled applications; the last

section shows how to develop a simple web service for the valuation of European
