[Python-ideas] pep 397

hello, *the pep 397 says that any python script is able to choose the language version which will run it, between all the versions installed on the computer, using on windows a launcher in the "C:\windows" folder.* can the idle version be chosen like this too, or can the idle "run" command do it? (except it is already like this and I have a problem) thank you, and have a nice day/evening! (and sorry if this sounds irritating)
