I recently visited the Python site, and noticed that a new version, 3.4.1 had come out.
My Ubuntu 14.04 had 3.4.0, so I downloaded 3.4.1 and installed it.
When I open IDLE, it showed 3.4.0, but when I open a terminal and type
python3, it shows 3.4.1.
I re-installed IDLE, then I searched for IDLE 3.4.1 Ubuntu, but I did not get anything.
I got Debian's packages site for the
IDLE 3.4.1.deb file, so I downloaded that.
I installed it, and yet IDLE showed 3.4.0, when I checked the Ubuntu Software Center, and it showed idle-python3.4 3.4.1-6 version so it should work.
Looks like typing
python340 just returns errors.
python3 gives me python 3.4.1 and of course
python gives me python 2.7.
It is like python 3.4.0 is not there but IDLE is still able to somehow access to it
In PyCharm there is an option to choose which Python Interpreter you want to use, I get 2.7 and 3.4.0 there.
