Learn how to use design principles to create more flexible, maintainable, higher-quality object-oriented software. You may be familiar with the fundamental concepts of object-oriented design—inheritance, encapsulation, polymorphism, and abstraction—but there is a set of higher-level design principles that can be used to take your design to the next level. Design principles guide your design decisions to produce software that is more reliable,...

You're not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns—the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on...something else. Something

It's no secret the world around you is becoming more connected, more configurable, more programmable, more computational. You can remain a passive participant, or you can learn to code. With Head First Learn to Code you'll learn how to think computationally and how to write code to make your computer, mobile device, or anything with a CPU do things for you. Using the Python programming language, you'll learn step by step the core concepts of programming...
