I answered a question that involved a very basic python issue. A user nominated it for closure, and if we look at the specific "on topic" points, he was correct. Currently, our on topic points are listed as:
- Raspberry Pi hardware, including GPIO and other related electronics.
- Raspberry Pi peripherals.
- Software specific to the Raspberry Pi.
- Operating Systems built for the Raspberry Pi.
The code the OP listed was copy and pasted from the Raspberry Pi Foundation's documentation. If the OP had asked the question on StackOverflow, and referenced the manual (as they did/should), I have no doubt it would have been migrated here in minutes. The code may not be specific to the RPi, but the source material is.
With that in mind, I voted to leave the question open, and I think we should consider officially including Questions about materials published or provided by the Raspberry Pi Foundation as an official topic.
