Python beyond the basics: Scaling Python with generators
Writing expressive, highly scalable code
Whether we like it or not, we’re in the age of big data. But big data is not just a buzzword; from now on, many of the programs you write will need to be able to process more data than ever before. So what's the best way to ensure that your code is scalable and high performing? The answer lies in a rich, powerful, and surprisingly underused feature of Python: the generator function.
In this hands-on three-hour course, expert Pythonista Aaron Maxwell walks you through Python's generator function and teaches you how to use generators to create powerful, highly expressive code. You'll discover how generators can profoundly improve the scalability and performance of all the code you write, from scripts to large applications, and learn how to improve the organization, composability, and expressiveness of your code. Along the way, you'll explore rarely taught generator design patterns that you can put into use immediately.
What you'll learn-and how you can apply it
By the end of this live, online course, you’ll understand:
- How Python’s mysterious generators really work
- The key design patterns made possible by generator functions
- How to create more responsive and scalable Python software
And you’ll be able to:
- Write code that automatically and gracefully handles increasing magnitudes of data
- Create interlocking Python components
- Write Python code that’s concise, readable, and highly maintainable
- Advise your teammates on powerful Python patterns and crucial best practices
This training course is for you because...
- You're a web developer using Python frameworks, and you want to expand your knowledge.
- You’re a QA engineer using Python for scripting and writing tests, and you want to explore Python's generator function in more detail.
- You’re a data scientist using Python, and you want to get more done, faster.
- You’re a software engineer aiming to be more productive and write more robust, reliable, and maintainable Python code.
- You want to improve your Python knowledge to ace an interview or land that dream job.
- You want to deeply understand the Python language and ecosystem and how to use it to its fullest potential.
- Complete the Python Labs Prep
- An intermediate understanding of Python (e.g., the ability to write simple Python programs using lists and dictionaries)
- Familiarity with basic types (int, str, float, etc.)
- Experience using modules in the standard library
Materials or downloads needed in advance:
A machine with Python 3 (3.6+) or Python 2.7 installed along with the Python-aware IDE or editor of your choice (e.g., PyCharm)—You will be able to do the programming exercises in either version of Python. Since almost everything in the course applies to both versions, the class will be taught primarily using 3, pointing out where 2.7 is different as we go along. You should be able to open a Python interactive interpreter on the command line and run simple programs ("python3 helloworld.py") either on the command line or in your IDE. On Windows, you will need to set your system path.
