This Sunday, start writing better Python code

Want to write better, more readable, more flexible, and more maintainable Python code?

Well, testing is the key to that, and pytest is the key to testing in Python.

This is just a quick reminder that my pytest course will be given live on this coming Sunday, September 13th.

This course is for you if:

  • You want to write more robust Python code via testing
  • You want to understand how to use pytest
  • You want to understand some of pytest‘s more sophisticated features, such as parametrized tests and fixtures

Because it’s a live class, there will be plenty of opportunity for questions and answers. And of course, there will be lots of exercises as well, so that you can practice what you’ve learned.

Questions? Just contact me at reuven@lerner.co.il. I’ll be happy to answer. Or check out the course page at https://store.lerner.co.il/pytest, which has a FAQ.

Master object-oriented Python with Weekly Python Exercise — starting September 8th

Object-oriented programming has been around for several decades. As a result, it has become easier to organize, maintain, and reuse code.

Well, sort of. Perhaps the word “easier” isn’t quite right.

I’ve met many people who tried to learn programming, and especially object-oriented programming, in such languages as C++, Java, and C#, and got lost with all of the syntax and terminology.

The good news is that Python’s objects are much more straightforward to learn and use than those other languages. But there are still concepts to master, as well as syntax and keywords associated with objects. And even after you’ve learned how to work with classes, instances, and methods in Python… it can still be a bit daunting and unfamiliar.

Does that describe you? Are you somewhat familiar with Python’s objects, but not fluent enough to use them confidently in your own projects? If so, then you’re not alone. Moreover, there’s a good way to become more fluent, and to gain confidence when working with Python’s objects: Practice. And not just practice, but guided practice, ideally with peers learning alongside you.

If this does describe you, then you should check out the upcoming cohort of Weekly Python Exercise, which will concentrate on object-oriented programming for beginners. For 15 weeks, you’ll get a new problem on each Tuesday, and see the solution on the following Monday. You’ll participate in our exclusive online forum, exchanging ideas and solutions with other students. And you’ll be invited to live, monthly office hours at which we can discuss any Python topics you want.

Join Weekly Python Exercise A3: Objects for beginners

But don’t delay: WPE A3 (“Objects for beginners”) starts on Tuesday, September 8th, and won’t be offered until the autumn of 2021. Register, or just learn more, at https://store.lerner.co.il/wpe-a3. Or if you have questions, contact me at reuven@lerner.co.il or on Twitter as @reuvenmlerner.

New course: Testing your Python programs with pytest

My first job was at a company that wrote software for hospitals. As you can imagine, our work needed to be really reliable — so we had an entire team dedicated to quality assurance (QA). Their job was to run our software for months at a time, given many different inputs, and to make sure that it didn’t cause trouble.  I can tell you that the head of QA was the most feared person in my department. And yet, we all knew that his job was of utmost importance. If it weren’t for him, buggy software could go out the door, with catastrophic effects for people being treated in hospitals around the world.

More than 25 years have passed since I had that job. And while not every program directly affects people’s lives,  there’s no doubt that software is hugely influential. Buggy programs can not only hurt people, but lose money, destroy documents, give incorrect projections, and use up valuable resources.

It’s no surprise, then, that testing continues to be really important. And while there are lots of  people still working in QA, much of that burden is now shouldered by individual developers, who have to test the code that they wrote themselves.  That’s right — you can test your own code, to make sure it does what it’s supposed to do (and  doesn’t do what it’s not supposed to do).

Over the last few years, I’ve joined a large and growing number of Python developers using pytest — a test system written in Python, designed to be used by Python developers. And I have to say, pytest is truly amazing: It’s easy to learn, very powerful, and has a huge community that contributes a wide variety of plugins for everyone to use.

Earlier this month, I asked subscribers to my “Better developers” list what topics they would like to learn in a series of live courses I’m starting to offer. And overwhelmingly, people wanted to learn pytest.

I’m thus delighted to announce that on Sunday, September 13th, I’ll be teaching a live, four-hour online course about pytest: “Test your Python code with pytest” If you’ve always wanted to learn about testing in general, or pytest in particular, this course will jump-start you into understanding the hows (and whys) of testing your Python code.

A few quick points:

  • The course will take place at 6 p.m. in Israel (where I live), which is 4 p.m. in London, 11 a.m. Eastern, and 8 a.m. Pacific. I hope that you’ll be able to join me live, so that you can participate and ask questions.
  • Even if you can’t join me live, the recording will be available to everyone who has enrolled. And that recording will be available forever — if you don’t have a chance to watch it right away, or want to review the material later on.
  • The course is 4 hours long, but will include a good number of hands-on exercises.

You’ll walk out of this course knowing how to use pytest, and how to apply that knowledge to your own programs — making them more robust, and saving you time down the road.

I’m really excited about pytest, and also excited to offer courses in this new format.  Please join me, and learn how to write better, more reliable code in less time.

“Python Workout” is available in print!

If you’re like a lot of people, you’re able to get things done in Python, thanks to a combination of intuition, searching on Stack Overflow, and messing around. But you don’t feel fluent with the language, in that you’re always wondering just why things work the way they do.

The way to overcome this is practice. Lots of practice.

My book, “Python Workout,” is all about learning through such practice. In 50 exercises (and another 150 extensions to these exercises), you improve your Python skills, one exercise at a time.

Reuven Lerner holds a printed copy of "Python Workout"

And as of earlier this week, “Python Workout” is now available in print, as well as online. It has tons of features — from walkthroughs on the “Python Tutor” site to screencasts of me solving the exercises — to help improve your fluency and understanding when programming in Python.

Check out Python Workout, at https://PythonWorkout.com/!

Level up your Python skills with a supercharged Humble Bundle!

Buying the bundle not only gives you access to some amazing Python training at a great price. It also supports the Python Software Foundation (which handles the administrative side of the Python language and ecosystem) and Race Forward (which works to improve race relations in the US).

There are three tiers to the bundle, and I have a course in each one:

  1. Comprehending Comprehensions
  2. Object-oriented Python
  3. Any one cohort of Weekly Python Exercise

Included in the bundles are also courses and books from Michael Kennedy, Trey Hunner, Matt Harrison, PyBites (Bob and Julian), Real Python (Dan Bader), and Cory Althoff. Plus it includes a subscription to the PyCharm editor.
