This book is a straightforward guide to the Python programming language and programming techniques. It covers all of the practical programming skills that may be required up to GCSE level and for those at AS Level with limited exposure to Python. It is suitable for both experienced programmers, students or individuals with very little or no programming experience in other languages. It teaches basic syntax and programming techniques, and introduces three inbuilt Python modules: Tkinter, used for building a graphical user interface, which is an option that some users may like to include in their project work.  SQLite, which enables the creation and processing of a database from within a Python program. This provides an alternative to writing to a text file when data needs to be stored and retrieved. pdb, Python’s debugging module, which can be used to help find elusive logic errors. - from Amzon
