The recommendation by the CPython team, expressed in their build scripts, is to install Python 3 as `python3`, and we try to follow upstream as closely as we can. I'd guess their reason is long-term compatibility with existing Python software that assumes `python` is Python 2. We offer Python 3 as `python` in the special package python-wrapper. In general, Guix does default to Python 3. If you want to use Python 2 in a package or profile, you have to specify it. Otherwise, using the package named 'python' will give you Python 3. If there are several versions of a Guix package with the same name, Guix uses the latest version by default.
