Documentation: Python 3.6 with Debian stretch

[COhsrt]

If you are using Debian Stretch you will need python3.6.
This is packaged for testing already, so you can use testing.
To do so, execute those things as root:

# Add Testing Repository
echo "deb http://ftp.debian.org/debian testing main non-free contrib" > /etc/apt/sources.list.d/testing
# Get your current installed codename
codename=$(lsb_release -c |awk '{print $2}')
# Pin your current installation to $codename
echo "APT::Default-Release \"${codename}\";" > /etc/apt/apt.conf.d/99DefaultRLS
# Update your repository infos
apt-get update
# Install python3.6 from testing
apt-get install python3.6 -t testing

You may want to say yes to all questions asked while installing python3.6
