title: How to link multiple scripts?
body: <p>I would like to separate my functions into different files like I do with c++ (a driver file and a file for different categories of functions that I end up linking together upon compilation).</p>
  
  <p>Let's suppose I want to create a simple 'driver' file which launches the main program and a 'function' file which includes simple functions which are called by the driver and other functions within the 'function' file.</p>
  
  <p>How should I do this? Since python is not compiled, how do I link files together?</p>
