Built-in Section Types
Section
With Callable and Parameters
This section has a callable of sklearn.cluster.KMeans
, and 9 parameters:

It's equivalent to:
clusterer = sklearn.cluster.KMeans(n_clusters=15, max_iter=1000)
Without Callable
This section has no callable, and 2 parameters:

It's equivalent to:
important_vars = {"batch_size": 64, "iterations": 10000}
Without Parameters
If you're sure your callable won't need any parameters, you can remove parameters entirely from the section. Currently the only benefit of doing this is that it's visually cleaner:

It's equivalent to:
random_number = numpy.random.random()
List Root
A list root represents a list of sections, list roots, or dictionary roots.
Dictionary Root
Group
Global Variables
A Global Variables
section is like a section without a callable. The difference is that the parameters are not created inside of a dictionary.

It's equivalent to:
N = 45
seed = 1234
root_path = "/tmp"
