Talk Python – Python Memory Management and Tips Course

Python 内存管理对于大多数开发人员来说通常是一个黑匣子。您可能知道 Python 使用引用计数，但是您如何才能最有效地编写代码来使用它呢？你知道它也使用垃圾收集吗？你知道什么时候开始它及其性能影响吗？通过本课程，您将学习所有这些概念以及更多内容。您将通过具体的代码示例来探索它们，而不仅仅是理论。并且您将学习优化您的代码以使用更少的内存并更快地运行。

这门非常独特的课程不仅将教授 Python 内存管理的工作原理以及如何创建在该世界中运行良好的代码，还将提供许多具体的技术、工具、设计模式等，使您的程序具有更高的内存效率和计算速度引导。

如果 Python 内存（分配、清理等）一直感觉像是一个奇怪的黑盒子，您不得不认为这是理所当然的，请加入本课程并打开那个盒子。Python 的运行时行为有许多美丽而有趣的方面，使您的代码能够运行。您应该了解代表您发生的事情。

Course Summary
Python memory management is often a black box to most developers. You probably know that Python uses reference counting, but how can you write code most efficiently to work with it? Did you know it also uses garbage collection? Do you know when that kicks it and its performance implications? With this course, you’ll learn all of these concepts and more. You will explore them with concrete code examples, not just theories. And you will learn to optimize your code to both use less memory and to run faster.
What students are saying
Can’t recommend this highly enough to anyone who wants to learn to code or learn Python in particular. One of Michael’s courses changed my career. Can’t say enough good things about Talk Python training.

What’s this course about and how is it different?
This very unique course will teach not just how Python memory management works and how to create code that functions well within that world, it will provide many concrete techniques, tools, design patterns, and more to make your programs more memory efficient and computationally faster to boot.

If Python memory (allocations, clean up, and so on) has always felt like a weird black box that you have had to take for granted, join this course and open that box. There are many beautiful and interesting aspects of Python’s runtime behavior making your code run. You should understand what’s happening on your behalf.

What topics are covered
In this course, you will:

Learn how Python variables and data structures actually look in the CPython layer
See how the small object allocator treats most objects differently than your intuition
Understand Python’s memory allocation primitives: blocks, pools, and arenas
Locate the elements on C code responsible for Python memory behavior
See reference counting in action with live code explorations
Discover why reference counting alone is not enough for memory cleanup
Work with Python’s GC and see when it’s needed, and when it’s not
Compare different data structures to get a sense of their relative size
Use multiple clever but simple techniques to massively reduce memory during function calls
Lighten up your classes with properties
Leverage multiple memory profilers to investigate memory usage line by line and over time
And lots more
View the full course outline.

Who is this course for?
This course is for anyone who wants to understand how Python memory is managed and make their code more efficient and faster. If you’re tired of Python memory being a black box hiding its behavior, turn on the light with this course.

The student requirements are quite light for this course. You’ll need Basic Python language knowledge:

Classes
Functions
Properties
Variables
Loops
Iteration
Note: All software used during this course, including editors, Python language, etc., are 100% free and open source. You won’t have to buy anything to take the course.
