title: Pycharm: run only part of my Python file
body: <p>Is it possible to run only a part of a program in PyCharm?</p>
  
  <p>In other editors there is something like a cell which I can run, but I can't find such an option in PyCharm?</p>
  
  <p>If this function doesn't exist it would be a huge drawback for me... Because for my data analysis I very often only need to run the last few lines of my code.</p>
