Python3 is not in the official repos at all for either RHEL 6 or 7. Certainly not 4 or 5. It is, however, available in EPEL repository. EPEL is associated loosely with Red Hat, but it's by no means and officially-supported repository, and many organizations may have policies disallowing its use, or the use of any other third-party repo, for security and stability reasons. Docker might be another possibility for using and deploying Python3 apps in RHEL, although Docker itself is a third-party installation, although from a corporate point of view, since Docker is available with commercial support, it may be allowed. Also Red Hat has a repo called the "Software Collections Library" that contains up-to-date compilers and languages, including Python 3.6. However by design these packages install into specialized, self-contained environments (not in the system path or library search path) so as not to conflict in any way with system versions. As such they are a bit awkward to deal with, particularly if you want to build applications using Python 3.6 from the SCL and run them normally in RHEL. You'd need a wrapper script to set up the runtime environment before running the Python script. -- https://mail.python.org/mailman/listinfo/python-list
