[FIXED] What are fallback completions in Spyder?

Issue

There is an option in the Spyder IDE (Tools->Preferences->Completion and linting->Advanced) to activate fallback completions:

What are fallback completions, how are they supposed to work and help? I have googled it and not found a description.

Note this question was inspired by this question complaining (implicitly) about fallback completions: How to disable keyword / text suggestion in Spyder 4?

There, it isn't really explained what this feature is supposed to be, how it is supposed to work, but basically how to turn it off using the above interface. I am not trying to turn them off I am trying to find out what exactly are fallback completions, and how are they different from other types of completion going on?

Solution

(Spyder maintainer here) Fallback completions are those completions provided by the tokens present in the file (i.e. any word on it, be it code, comments or strings), plus some Python builtin keywords (e.g. finally).
