Python3.5 in jessie?

Debugged your code inside lxc-container Ubuntu. Then set up a combat server container with jessie. Added

% cat /etc/apt/sources.list | grep back
deb [arch=amd64] jessie-backports main contrib non-free

Doing an update. Verify via the website that in testing there is a python3 package.5:

Package python3.5
Jessie (testing) (python): Interactive high-level object-oriented language (version 3.5)
3.5.3-1: amd64 arm64 armel armhf i386 mips mips64el mipsel ppc64el s390x

But to find it in backports fails.

% apt-t wheezy-backports search python 3.5

It turns out that the package is in testing but it is not in the backports. How to be in this situation? Need best way to install 3.5 regular means.

For this there is a mechanism for "Pinning", the main thing to remember is that in the available version of that package will be visible including from added repositories with a lower priority and do not update what can a simple apt upgrade, apt perfectly he understands.
