title: run a simple python script in ios
body: <p>I want to run a python script on ios.
  I don't want to write the whole Application in Python just a little part of it.  </p>
  
  <p>I have tried to understand PyObjC but it is not that easy.</p>
  
  <p>Could you give me an example, please? I would like to save the result for the following method in a <code>NSString</code> variable. </p>
  
  <pre><code>def doSomething():
     someInfos = "test"
     return someInfos
  </code></pre>
