title: How to save Python coding in Command Prompt as a file?
body: <p>I just typed an example from a book in Python34 of a running Command Prompt.</p>
  
  <p>but now I want to save this python program as file for future uses. Since I have never used Command Prompt before and I also searched online but most of them cannot answer.</p>
  
  <p>Can anyone show the solution here? Thanks. </p>
