/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?
Question about using python, including Idle, should be directed to python-list. Quick answers to what seem to be separate questions. 1. At the command line, one select the version of a module to run by selecting the version of python to run. Idle is no different from any other module intended to be directly run. For me, C:\Users\Terry>py -2 -m idlelib.idle # starts Idle in 2.7.9 C:\Users\Terry>py -3 -m idlelib # starts Idle in 3.4.2 On Windows, I pin the Start -> Pythonx.y -> Idle x.y icons to my task bar so I can select either python + idle combination with a mouse click. 2. Selecting F5 or Run-module in an Idle editor runs the editor buffer contents with the same version of python as is running Idle. I have considered adding 'Run with x.y' options according to what is installed, but that is pie-in-the-sky at the moment. -- Terry Jan Reedy
