I have python 2 7 13 and 3 6 2 both installed   Install Anaconda for python 3 first and then you can use conda syntax to get 2 7   My install used  conda create -n py27 python 2 7 13 anaconda

Yes you can   You don t have to download both Anaconda    Only you need to download one of the version of Anaconda and need activate other version of Anaconda python   If you have Python 3  you can set up a Python 2 kernel like this   python2 -m pip install ipykernel  python2 -m ipykernel install --user   If you have Python 2    python3 -m pip install ipykernel  python3 -m ipykernel install --user   Then you will be able to see both version of Python   If you are using Anaconda Spyder then you should swap version here     If you are using Jupiter then check here     Note  If your Jupiter or Anaconda already open after installation you need to restart again  Then you will be able to see

My understanding is you don t need to install Anaconda again to start using a different version of python  Instead  conda has the ability to separately manage python 2 and 3 environments

I use both depending on who in my department I am helping  Some people prefer 2 7  others 3 5   Anyway  I use Anaconda and my default installation is 3 5  I use environments for other versions of python  packages  etc   So for example  when I wanted to start using python 2 7 I ran    conda create -n Python27 python 2 7   This creates a new environment named Python27 and installs Python version 2 7  You can add arguments to that line for installing other packages by default or just start from scratch  The environment will automatically activate  to deactivate simply type deactivate  windows  or source deactivate  linux  osx  in the command line  To activate in the future type activate Python27  windows  or source activate Python27  linux  osx   I would recommend reading the documentation for Managing Environments in Anaconda  if you choose to take that route   Update  As of conda version 4 6 you can now use conda activate and conda deactivate  The use of source is now deprecated and will eventually be removed

Yes  It should be alright to have both versions installed  It s actually pretty much expected nowadays  A lot of stuff is written in 2 7  but 3 5 is becoming the norm  I would recommend updating all your python to 3 5 ASAP  though

Anaconda is made for the purpose you are asking  It is also an environment manager  It separates out environments  It was made because stable and legacy packages were not supported with newer unstable versions of host languages  therefore a software was required that could separate and manage these versions on the same machine without the need to reinstall or uninstall individual host programming languages environments   You can find creation deletion of environments in the Anaconda documentation    Hope this helped
