I want to use the cygwin installer to get a newer version of python3. I downloaded the latest cygwin setup tool (x86 32 bit) from http://cygwin.com/install.html. When I look at packages to install, the current python3 is listed as 3.2.3-1 and I already have this version installed.
Edit: I checked https://cygwin.com/packages/ and it appears that 3.2 is indeed the latest version available. If I can't use the cygwin installer, is there a way to get python3.4 on my cygwin file system that isn't too hacky?
As of today, you're stuck. I only see 3.2 as well. There's nothing stopping you from building/installing a later python into Cygwin as you would into any other *nix.
There was some chatter, but no answer, here about installing python 3.3 into Cyg that may get you started.
Edit (June 2015) Python 3.4.3 is now available via cygwin package installer.
