Samenvatting

All You Need to Know, and Nothing You Don't, to Solve Real Problems with Python

Python is one of the most popular programming languages in the world, used for everything from shell scripts to web development to data science. As a result, Python is a great language to learn, but you don't need to learn "everything" to get started, just how to use it efficiently to solve real problems. In Learn Enough Python to Be Dangerous, renowned instructor Michael Hartl teaches the specific concepts, skills, and approaches you need to be professionally productive.

Even if you've never programmed before, Hartl helps you quickly build technical sophistication and master the lore you need to succeed. Hartl introduces Python both as a general-purpose language and as a specialist tool for web development and data science, presenting focused examples and exercises that help you internalize what matters, without wasting time on details pros don't care about. Soon, it'll be like you were born knowing this stuff--and you'll be suddenly, seriously dangerous.

Learn enough about . . . Applying core Python concepts with the interactive interpreter and command line Writing object-oriented code with Python's native objects Developing and publishing self-contained Python packages Using elegant, powerful functional programming techniques, including Python comprehensions Building new objects, and extending them via Test-Driven Development (TDD) Leveraging Python's exceptional shell scripting capabilities Creating and deploying a full web app, using routes, layouts, templates, and forms Getting started with data-science tools for numerical computations, data visualization, data analysis, and machine learning Mastering concrete and informal skills every developer needs

Michael Hartl's Learn Enough Series includes books and video courses that focus on the most important parts of each subject, so you don't have to learn everything to get started--you just have to learn enough to be dangerous and solve technical problems yourself.
