The doc string tell that count will > return the number of substring in the master string, if we spoke about > substring i count 3 substring... depends on how you define "number of substring", I mean, overlapping or not. FWIW, I agree that this may be somewhat unintuitive, and would at least require a little bit more precision in the docstring. > Can someone explain me this?
