We've decided to include the solutions to the practice exercises. Initially, the intention was to omit them. It can be frustrating. However, it's working your way through that actually drives the learning. It feels good to see the solution, but to make it really click, you have to make it your own and work your way through it.
That said, a large number of students have requested that I add these and so here they are.
But, I want to you be sure you want to go down this path. Ideally, this is a check my solution type of thing. So we have made the steps a little bit manual. To see the solution, you have to check out the with_solutions branch. They do no appear in the default master branch (this one).
You can do this on GitHub by just using the branch dropdown like this:
Then you will see a solutions folder below this one.
Best of luck on the course, Michael!
