[Python-ideas] Suggestion: Windows launcher default to not using pre-releases by default

Currently the py[w] command will launch the latest python by default however I feel that this discourages the testing of pre-releases & release candidates as once they are installed they will become the default. What I would like is for the default to be the highest version number of a full release but the user to be able to specify a specific version even if it is a pre-release. The currently py or py -3 would give python 3.7 (if installed) but py -3.8 would give the pre-release/release candidate if installed. Any thoughts on whether this would be a good idea - I am quite willing to undertake the changes. Steve Barnes
