title: Installing python 3.5 on Linux Mint 17.3
body: <p>I am very new to linux and want to use python as it is the language I am learning at school. I have looked online and checked my current version is 2.7 which is no good to me as I am learning python 3. However, I have heard that changing your systems python version can be very bad so I don't know what to do :(. Also, is there a way to use it like you can in windows such as opening the IDLE and opening a new shell to write your code in there, because all I can find on the internet is how to write code in python through the terminal which I do not want to do.</p>
  
  <p>Thanks.</p>
