How does the SDLC contribute to python?

Does the SDLC contribute to python and if so, in what ways.

What does SDLC mean?

SDLC = Systems/software Developement Life Cycle.

SDLC is not a methodology per se, but rather a description of the phases that a methodology should address.

Python is not a product or integrated information system per se, so the question does not make a whole lot of sense to me. Domenic, I suggest you read the devguide for some idea of how it is developed. Look at the ideas channel here, read some PEPs, and view some issues and pull requests.
