title: how to save codes history in QT Console python?
body: <p>I just switched from R to Python, and find Jupyter Qt Console is really handy and helpful for running codes line by line. </p>
  
  <p>But I have a question: how to save the codes already input? I mean just like Rstudio, the top left part is the code editor, the bottom left is the console window. So I can get a whole picture of my codes and debug them line by line.</p>
  
  <p>I have tried Spyder(Rstudio like), but it has some problems in auto-completion. Qt console is much better. Is there a way to combine a text editor and qt console into one single IDE?  </p>
  
  <p>Thanks!</p>
