Radosław Jankiewicz - Writing quality code The quality of written code is an important factor in a final success of a software project. Perhaps there is no universal definition of high quality code, however usually it's characterized as clear and readable, well-designed, well tested and documented, easier to debug, maintain and extend, etc. Python was designed to be a highly readable language that would make it easier to develop high quality code. Nevertheless, programming language is only a tool in a software development process and in the end the quality of code depends mostly on its author's concept and decisions he make. In this talk I would like to present some of ideas, techniques and tools for improving the quality of written code, tried out with a good result in everyday work on developing software in Python.
