Yes, Weekly Python Exercise costs $180. 

Right now, you're just signing up to be informed when registration has opened for the next cohort; this sign-up process is free.  You'll have an opportunity down the road (probably starting in mid-July) to decide if WPE is for you, and  to pay at that time.

There are discounts for students, pensioners, groups, and people living in countries with a non-Western standard of living. Details on obtaining such discounts will be sent out with the course announcement.

WPE is aimed at people with an intermediate knowledge of Python: You're not a beginner, and you have a good understanding of the built-in data types, writing functions, and of working with objects.  But working with more advanced data structures, list comprehensions, and such topics as iterators, generators, and decorators are a bit beyond what you've comfortably dealt with so far.

I've had people participate in WPE at even a beginner level, and they have gotten quite a bit out of the course — but they also admit that they often wait to discuss solutions in the forum, research topics on their own, or spend far more time on the exercises than I would expect.

If you don't think you're getting value from Weekly Python Exercise, then ask for a refund, and I'll give you one.

I use Python 3 (as of this writing, 3.7). 

No, of course not!  But I'm hoping that lots of people will do so.  In my career as a Python trainer, it's clear to me that people who solve exercises together both learn and retain more than those who don't. I strongly encourage participants in my in-person classes to work in pairs, and while doing so online might be hard, I hope that the forum can provide something akin to those interactions.

If you can't make it to office hours, then submit your questions in writing, and I'll answer them — then, when you have a chance, you can view the recording.

Yes and no: The exercises, forum, and live office hours will be tied to one another, and will reflect the current (weekly) exercise.

But no one is forcing you to do the exercises with everyone else!  You can skip exercises, and do them later than everyone else.  The forum, and video recordings from office hours, will be available for you to use, watch, and review forever, as far as I'm concerned.  So there's no pressure on that front.

That said, I do believe that there's a value in dedicating a bit of time each week to improving your craft and learning new things.  WPE is designed to take up only an hour or so each week, which I hope you'll agree is a worthwhile investment in your career.

You bet!  Just go here:

Sign up for this mini version, and you'll get two exercises (and their solutions), in the same style as the real WPE.  This sample squeezes it all into five days.

Yes — if you join with a group of 5 or more, each person gets 20% off.

I also offer my standard 20% discount to students and pensioners. 

I also offer my standard "parity pricing" discount to anyone currently living outside of the 30 wealthiest countries in the world.

Interested in any of these?  Just contact me via e-mail, and I'll be delighted to provide you with the appropriate coupon code.

Office hours will be held 1-2 times each month.  I'll try to vary the days and times, so that no matter where you live in the world, you'll be able to participate at least occasionally.
