title: The best way to call programs from cx_freeze
body: <p>I have an ad hoc solution for a group of my scripts (a Tkinter main menu calling programs with something like this):</p>
  
  <pre><code>def record_data():
      os.system('python record_data.py')
  </code></pre>
  
  <p>And it works while I don't make any attempts to freeze the program. Clicking a button with a function attached to it doesn`t work after freezing. What is the best way to call a program even after cx_freezing?</p>
