I am amazed that `...` is a valid syntax in Python, not a pseudo grammar.

This library is impressive, I appreciate it and I will apply it to my project.

What's the difference between '...' and the more common 'pass'?

[hoosieree]

I find students correctly infer what to do with "..." whereas they were afraid to touch "pass".

E.g, if I gave them this:

    def foo(x):
      ...  #add your implementation here
    
    def bar(x):
      pass #add your implementation here

I'd get back this:

    def foo(x):
      return x+1
      
    def bar(x):
      return x+1
      pass

In code, using ... implies that the code is yet to be written. pass means it's explicitly a noop.

In this case, functionally, nothing. Some other commenters have suggested it does something interesting by implying "AI will provide the logic," whereas "pass" doesn't necessarily do that.
