title: How do I make a Jupylet app working inside of an if statement in a Jupyter notebook
body: <p>I am using a Jupylet app inside of my notebook. If I run <code>app.run()</code> inside of a cell it works fine, but if I trigger the run from an if statement as in my example code, it does nothing. There are no errors, but the app does not show up. How can I solve this?</p>
  <pre class="lang-py prettyprint-override"><code>    import sys
      import os
      sys.path.insert(0, os.path.abspath('./..'))
      from jupylet.label import Label
      from jupylet.app import App
      
      app = App(width=320, height=64)
      hello = Label('hello, world', color='cyan', font_size=32, x=app.width, y=22)
      
      @app.run_me_every(1/24)
      def scroll(ct, dt):
          hello.x -= dt * 48
          if hello.right &lt; 0:
              hello.x = app.width
              
      @app.event
      def render(ct, dt):
          app.window.clear()
          hello.draw() 
      
      c = 3
      if c == 3:
          app.run()
  </code></pre>
