About this course
For people whose Python works and lives in one file on one laptop. Ten weeks later that file installs with one command, explains its own errors to whoever runs it and ships a new version whenever you push a tag.

The tutor asked what I thought the error meant before saying anything. Annoying on day one; by week three I was doing it unasked.
Grace W.Career changer

I finished with a repository I could show in interviews. Two interviewers asked about the project before they asked about anything else on my résumé, and one of them had read the tests. I had spent eight years in retail management, and this was the first thing I had ever built that a stranger could download, install and run on their own machine.

The exercises break things on purpose. Fixing the failing run in module three taught me more than any of the lectures I have sat through.
Pete L.Senior engineer

Too basic for me. The last module is what I came for, and it is short.
Mei C.Software engineer

Tomás reviews the project the way a senior colleague would: short comments, each pointing at one line of your code and asking why it is there.
Nadia B.DevOps engineer

I use something from this course every week. The notes on failure paid for it.

Enrolling
What people ask before they enroll
A person answers anything this list does not. Ask us.
Enough of the basics to follow along without stopping to look things up. Lesson one is free, so open that first: if its practice set feels routine to you, you are ready for the rest of the course.
Nothing expires. 10 weeks at 6 hours a week is the pace the course was planned at, and at 4 hours it takes 15 weeks. The panel above works out a finish date for whatever pace you give it.
A start date, a finish date and a live review of the week's work every Thursday, with the same 30 people from the first week to the last. The lessons and the tutor are the ones the self-paced track gets.
A certificate from the school that made the course, and the project the instructor's team reviewed. Each comes with a link that anyone, an employer included, can open and check in a few seconds.
Yes, within 30 days of enrolling, from your account page and with no form to fill in or reason to give. Lesson one is free with the tutor, so most people know the course suits them before they pay.
Waypoint Plus is $29 a month and opens this course along with every other. At $129 this one costs about 4 months of it, so buy it on its own if it is the only course you mean to take this year.
Watch lesson one tonight. Decide in the morning.
It opens with the tutor beside it and the practice set under it, and asks for no card. The other 22 lessons are $129 once, or part of Plus.
