The quickest way to learn the basics of Python.

Massimo Perga, Microsoft

This revision of Manning's popular The Quick Python Book offers a clear, crisp introduction to the elegant Python programming language and its famously easy-to-read syntax. Written for programmers new to Python, this updated edition covers features common to other languages concisely, while introducing Python's comprehensive standard functions library and unique features in detail.

After exploring Python's syntax, control flow, and basic data structures, the book shows how to create, test, and deploy full applications and larger code libraries. It addresses established Python features as well as the advanced object-oriented options available in Python 3. Along the way, you'll survey the current Python development landscape, including GUI programming, testing, database access, and web frameworks.
