For instance, if you installed Python 3.8 and then Python 3.9, the latter version would upgrade py. Whenever a new version of Python is installed, the py launcher will be updated, as long as the Python version being installed is newer than the py launcher. If you use just -2 or -3 as the version switch, Python will launch the most recent version of Python 2.x or Python 3.x, as indicated. In the above example, if we typed py -3.10, we’d get the 64-bit version of Python 3.10, because only the 64-bit version is present. If you don’t specify a bitness, and only one bitness of a particular version is installed, that bitness will be loaded by default. IDGįour examples of the py launcher in action. So if we just typed py -3.9, we’d get the 64-bit version of Python 3.9. On a 64-bit machine, that would be the 64-bit edition. Note that if you provide only a version number, and not a bitness indicator, you’ll default to whichever version of Python is native to your machine’s processor type. For instance, to launch the 64-bit edition of Python 3.9, you would type py -3.9-64. To invoke a specific edition of Python, type py followed by the switch in the left-hand column for the appropriate version. The interpreter marked with an asterisk is the default. You’ll be presented with a list of all the known interpreters in the system, their version numbers, and their full paths. To see which versions of Python are available to py, type py -0p.
py by itself will drop you into the Python REPL, which you can exit as you normally would by typing quit() or Ctrl-Z. When you type py at the command line, the launcher will invoke the current default Python interpreter.
