To be honest, for me it looks as very strange pattern… If one wants to have static container with functions, there is Enums or classes.

It’s most useful when you’re using some data you already have as the dictionary key. A usecase i had for this was a binary file parser with 10 types of event markers. It was originally coded with if/elif, but performance was a pretty big consideration. Using the event markers as keys to a dictionary dispatch improved performance by about 15% and made the code significantly more readable.
