About the Reviewers

Panagiota Katsikouli is a PhD researcher in the School of Informatics, University of Edinburgh, UK. Her work is related to developing techniques for the compact representation of location and signal data recorded in mobile sensing devices, such as smartphones or standalone sensors, in order to design and implement lightweight online and/or distributed algorithms to perform various analysis tasks, such as detecting popular paths and indoor localization, on the data. She has received her undergraduate diploma from the Polytechnic School of Patras, Greece, Department of Computer Engineering and Informatics, and her master's degree of computer technology from the same department. Panagiota, in her free time, enjoys writing Python games using the Tkinter library.

Erik S. Rapert is a pale, slim programmer and a twin who loves Linux and video games. He lives in Dallas with his wife, who is also a software engineer. Erik has a wide range of experience, which includes creating blinking LEDs using Arduino, building small desktop apps using Python and Tkinter, web development with PHP or Ruby, and developing cutting-edge virtual reality using C++. He has used a very broad range of programming languages, but Python is one of his favorites.

Thank you William C. Slater for teaching me how to write software. Thank you Andrew Closson for being a teacher. Thank you Ashley for being you.

Rapha?l Seban is a French man who is self-trained in computer science since 1981. He obtained a science degree of mathematics and physics in 1986 and then entered active life directly. A computer geek, he never stopped learning new concepts and is learning even today. He worked for two years with IA's R&D department as a software developer and research assistant. After that, in 2000, he decided to create his own company, RAF'INFO, where he worked until 2008.

Since May 2008, Rapha?l has mainly contributed to the open source community by developing free software on GitHub (https://github.com/tarball69) and providing help on technical forums.

His famous free software, tkRAD (https://github.com/tarball69/tkRAD/wiki), still remains one of the leading Tkinter Rapid Application Development libraries in Python's community, providing helpful services such as XML widget GUI building and a powerful event manager.

I would like to thank the Packt Publishing team for trusting my Python/Tkinter expertise, especially Bhaskar Chaudhary, the author, who made an actual effort to give his knowledge an educational purpose; Judie Jose, the project coordinator, for her kindness; and Dinesh Rathe, the reviewer acquisition executive who recruited me.
