In this chapter, you learned how to handle some of the popular embedded metadata formats, perform basic file signature analysis, and create frameworks in Python. Frameworks become a normal programming solution as programs increase in complexity. The code for this project can be downloaded from GitHub or Packt, as described in the Preface.
In the next chapter, you'll learn how to develop a basic graphical user interface, or GUI, in Python using the first-party TkInter module. This GUI will be responsible for converting timestamps of various types into a human-readable format.
