About the Book
The Python Apprentice together with The Python Journeyman and The Python Master comprise a trilogy of books on the Python programming language and the Python Standard Library. The material in these books is derived from Sixty North's popular and battle-tested training courses which have led thousands of programmers on a journey to being productive with Python.
Our books, which use Python 3, follow a spiral curriculum: We introduce topics gently and then revisit them on multiple occasions to add the depth required to support your progression as a Python developer. We've worked hard to structure the syllabus to avoid forward references. On only a few occasions do we require you to accept techniques on trust, before explaining them later; where we do, it's to deliberately establish good habits.
