The formatting has been well thought out. The main problems with Python formatting are copy and paste problems, source control merges, and relying on the count of invisible characters to determine indenting. Any time you're merging two bits of code, it's very easy for the indenting to get messed up. In go, that's not a problem, since the braces are the only thing that matter. This is also what allows gofmt to format your code for you.
I think you misunderstand slicing. It's very similar to python's slices, except that python makes a copy of the list and Go does not. This is a really nice feature for reducing data copies.
The default values are very useful in many situations, and code is often designed around the fact that uninitialized variables have specific values.
As for error handling, Go's error handling is one of its biggest strengths, in my opinion. You never have to worry that your function will exit out in the middle unexpectedly. This is really great when dealing with third party libraries, since you don't have to know if something 6 levels deep is going to throw an exception... if something returns an error, you can deal with it right there. I find I write much more reliable code in Go, because error handling is so much simpler.
