Märksõnad:
"A book of varied coding projects for readers who know a little Python already and want to expand their skills. Save shipwrecked sailors, discover exoplanets, and more, while gaining experience using free modules like OpenCV, NumPy, Pandas, NLTK, Bokeh, Beautiful Soup, and matplotlib"--

A project-based approach to learning Python programming for beginners. Intriguing projects teach you how to tackle challenging problems with code.

You've mastered the basics. Now you're ready to explore some of Python's more powerful tools. Real-World Python will show you how.

Through a series of hands-on projects, you'll investigate and solve real-world problems using sophisticated computer vision, machine learning, data analysis, and language processing tools. You'll be introduced to important modules like OpenCV, NumPy, Pandas, NLTK, Bokeh, Beautiful Soup, Requests, HoloViews, Tkinter, turtle, matplotlib, and more. You'll create complete, working programs and think through intriguing projects that show you how to:

  &;  Save shipwrecked sailors with an algorithm designed to prove the existence of God
  &;  Detect asteroids and comets moving against a starfield
  &;  Program a sentry gun to shoot your enemies and spare your friends
  &;  Select landing sites for a Mars probe using real NASA maps
  &;  Send unbreakable messages based on a book code
  &;  Survive a zombie outbreak using data science
  &;  Discover exoplanets and alien megastructures orbiting distant stars
  &;  Test the hypothesis that we're all living in a computer simulation
  &;  And more!

If you're tired of learning the bare essentials of Python programming with isolated snippets of code, you'll relish the relevant and geeky fun of Real-World Python!

Arvustused

"Python programmers with a little bit of experience, looking for a fun challenge that relates to real-world examples, should read [ this book]." Geek Tech Stuff

"I recommend this book for all Python learners!"   Kelly Paredes, Teaching Python podcast

"This is the most amazing book anyone could pick up if they are unsure about what machine learning job they should focus on." Ian Mizer, Atlanta Python Programmers Group

"Read this book and do the work. You will find yourself building programs that address real-world problems and readying yourself to attack similarly challenging problems in whatever field you are working." Sandra Henry-Stocker, Linux journalist, NetworkWorld (IDG)
