title: Shebang/choose what version of Python a script is going to run
body: <p>As a lot of people I have both the 2.7 and 3.5 version of python. Some code is backwards-compatible, some are not. This is because of the lack of modules that exist for 2.7 but not for 3.5. I therefore have a fair bit of scripts that are 2.7 and a fair bit that are 3.5. The default of .py extensions is the 3.5 version of python in my computer. My question is as follows: How can you "tell" the script to use another version of python(2.7 for instance) rather than the default I am using(3.5). I heard about Shebang, but it is Linux only.</p>
