title: Opening file from python
body: <p>In my python file, I create an *.bmp image, which I the open to check everything went fine.</p>
  
  <p>It is a bit of a hassle to open this each time I run my program (I know, I'm too lazy) and using show seems counterintuitive, since it freezes the execution and I can't keep it open. </p>
  
  <p>Which is the command in python to open files?, you know like a:</p>
  
  <pre><code>command='gedit file.txt'
  pythonmagic.execute(command)
  </code></pre>
  
  <p>Obviously pythonmagic and the syntax are the things I'm missing.</p>
  
  <p>Thanks a lot</p>
