title: How to update Python 2.7 to 3 in terminal
body: <p>I'm trying to run a python3 script through terminal on my mac, but every time I execute the file terminal uses Python 2.7 despite 3.7 being installed.</p>
  
  <p>I have read in other threads that python3 can be run by using the "python3" command, but this seems to load me into the python syntax with ">>>" at the beginning of every line</p>
  
  <p>Is there a way of running python 3 while using whatever syntax is native to terminal?</p>
  
  <p>Or as a last resort what is the command to run a .py file from the python syntax?</p>
