Inhalt: There are many principles that support good object-oriented design and programming. Five of these principles are described by SOLID: single responsibility, open-closed, Liskov substitution, interface segregation, and dependency inversion. These principles guide the creation of stable, scalable, and robust code. To incorporate SOLID into your own development workflow, Steven Lott has prepared a series of lessons that break down the principles one by one, with real-world examples. Learn how to use these principles in the design process, and to test the strength of your code along the way. Steven uses Python to demonstrate the concepts, but they're useful for any object-oriented programming language. Umfang: 01:45:37.00
Inhalt: Are you still using Python 2.7? If you've been meaning to make the jump to Python 3, but aren't entirely sure what's different in the latest version of this popular language-or how to migrate your code-then this course is for you. Instructor Steven Lott illuminates the differences between the two Python versions, going over elements such as changes to built-in Python functions and the Python standard library. He also walks through a number of ways to convert your Python 2.7 applications to Python 3, showing how to use packages like six, future, and 2to3. Along the way, Steven shares his own experiences with this transition, and offers helpful suggestions for enhancing the overall quality and performance of your code. Umfang: 02:39:56.00
Inhalt: Are you still using Python 2.7? Official support for this version ended in January 2020; upgrading is more important than ever. If you've been meaning to make the jump to Python 3, but aren't entirely sure how to use the new features-or how to migrate your existing code-then this course is for you. Instructor Steven Lott illuminates the differences between the two Python versions, going over changes to built-in Python functions and the Python standard library. He also walks through a number of ways to convert your Python 2.7 applications to Python 3, including manual rewrite and automated migration using packages like six, pytest, and 2to3. Along the way, Steven shares his own experiences with this transition and offers helpful suggestions for enhancing the overall quality and performance of your code. Umfang: 02:45:44
