title: How to run .py files on Windows/Anaconda terminal?
body: <p>So I installed Anaconda on my computer, and use Jupiter notebook to write a script.</p>
  
  <p>I have some .py files I want to run from Windows or Anaconda Terminal, just out of curiosity.</p>
  
  <p>Here are the error message I got -</p>
  
  <p>C:\Users\xxx\Documents>python ex1.py
  'python' is not recognized as an internal or external command,
  operable program or batch file.</p>
  
  <p>Is there a way that I can run python on Windows without messing up the path?</p>
