FAQs

Who should take this course?

This course is aimed at people who have a programming background, but are new to Python. My typical students are people with experience in C, C++, Java, and/or C#.

The content comes from the four-day "Intro Python" course I teach at companies around the world. I normally have some students without a strong programming background; many of them are able to get through the course (and enjoy it), but there are those who struggle.

If you aren't sure whether your background is strong enough, just e-mail me, and let's chat about it!

What version of Python do you use?

3.7, although I do briefly mention a new feature in 3.8. (I didn't have 3.8 running on my computer when producing the course.)

If you have Python 3.6 or above,then you're fine for this course.

Is there a “trial” version or sample?

No, but (a) you can view a number of the videos for free, without purchasing the course, and (b) I offer a 100% guaranteed refund if you need.

Is automated testing a part of this course?

No, but I am preparing a separate course on "pytest" that will cover functions (among other topics).

I live in Israel. How do you handle issues like VAT?

If you live in Israel, then please don't buy any of my products (including Weekly Python Exercise) via this online platform. I'm obligated to collect VAT from you, and then to pass it along to the government. Instead, please e-mail me for information about sending me a bank transfer. I'll then add you to the course, but we'll be able to handle it in the standard and legal way. I apologize for this frustration -- believe me, I wish that the platform I use for selling courses would support Israeli VAT, and I keep asking them to do so.

What if I find that the course is too easy or hard, or that I just dislike your jokes?

If you aren't satisfied with my course, then I'll refund your money. Just e-mail me. I believe that I'm offering a high-quality product, but I also know that it's not for everyone.

As for the jokes, people have been trying to help me for years. So far, my jokes have just gotten worse, not better. Oh, well.

I have other questions. What should I do?

Contact me at reuven@lerner.co.il, and let's see what I can do.
