Can't install Python 3.3.0

[Kipsley]

I have an old (Mid 2012) Mac Pro running Mojave 10.14.6 and have just installed a version of Qbittorrent. Trouble there is that the search engine in Qbittorrent requires (minimum) Python 3.3.0 in order to operate, and this old Mac currently uses Python 2.7.16.

So after doing lots of Googling and watching a few Youtube videos, I found my way to the Python website and found the Python installer for 3.3.0, (python-3.3.0-macosx10.6.dmg) then downloaded Python 3.3.0 for Mac x64bit. There were three versions of this and I downloaded all of them.

Python-3.3.0.tar.bz2
Python-3.3.0.tar.xz
Python-3.3.0.tgz

Great. But when I run the installer I get a message saying "Installation failed as there are no files to install", and I have no idea why.

The Installer and the Python files are right there in the downloads folder, and i did spend all last night Googling to find an answer but came up empty. I'm sure this question had been asked multiple times, but I'm not very tech savvy and just can't work out what I'm doing wrong.

Any advice would be greatly appreciated.

Requires minimum 3.3.0 means you can install any version equal or higher than that. Install latest stable release 3.13
