title: Adjusting dict values from another script on the fly
body: <p>I have an automation script containing objects with different dict values (file paths)</p>
  
  <p>From another script I need to take these values and amend the file path depending on the system OS. What I want is to iterate over my list of variables and amend the file path. </p>
  
  <p>For example:</p>
  
  <pre><code>varA = {"source": "arc:/resources/folder/image.png"}
  </code></pre>
  
  <p>I need this to be converted to ...</p>
  
  <pre><code>varA = {"source": "users/charrison/desktop/folder/image.png"}
  </code></pre>
  
  <p>So I need to iterate over my variable script changing just the beginning of the path name. Replace 'arc:/resources' with 'users/charrison/desktop'. Im using an automation software which collates all objects into one global script whilst my code is in another</p>
  
  <p>Please help</p>
