title: os.path.exists() for files in your Path?
body: <p>I commonly use <code>os.path.exists()</code> to check if a file is there before doing anything with it.</p>
  
  <p>I've run across a situation where I'm calling a executable that's in the configured env path, so it can be called without specifying the <code>abspath</code>.</p>
  
  <p>Is there something that can be done to check if the file exists before calling it?
  (I may fall back on <code>try/except</code>, but first I'm looking for a replacement for <code>os.path.exists()</code>)</p>
  
  <p>btw - I'm doing this on windows.</p>
