Is there an easy way of removing blank lines from IPython notebook?
I have picked up a habit of blank lines from web development and my fingers tend to hit enter automatically. This makes IPython notebooks less(by taking too much of my 14" screen), not more readable in most cases.
I was wondering if there is a way of automatically remove blank lines from the notebooks.
In notebooks, I think preferred way of splitting the code is by placing each separate method to a different cell.
Is commonly accepted style guide for notebooks or does PEP 8 apply as it is?
EDIT: I think question 2, Is answered by IPython docs. https://github.com/ipython/ipython/wiki/Dev:-Coding-style

“delete a cell in jupyter notebook” Code Answer's D+D(press the key twice when you are in command mode) to delete the selected cell.
You can also find Toggle Line Numbers under View on the top toolbar of the Jupyter notebook in your browser. This adds/removes the lines numbers in all notebook cells. For me, Esc + l only added/removed the line numbers of the active cell.
If you are talking about deleting the empty line from jupyter notebook which opens in web browser then press Esc and D (keyboard key) 2 times. You can also see all the keyboard shortcuts in the jupyter notebook file
Pressing Esc and D (2 times) will delete only blank lines starting from the beginning. It won't delete any lines which have some text or code. Show activity on this post. Pressing Esc and D (2 times) deletes the complete cell.
I encountered the same problem, but in my case I'm installing it using pip instead. When you open the jupyter notebook on you browser (regardless of browser) and it shows you blank jupyter, try to press ( CTRL + Shift + R) it will refresh the page and clear the cache in the page. It works for me after I keep installing and uninstalling jupyter.
1 to forward delete a line from the curser use Fn + command + delete. 2 to backward delete a line from the curser use command + delete. 3 to delete a whole cell use Esc + (d twice)
If you are talking about deleting the empty line from jupyter notebook which opens in web browser then press Esc and D(keyboard key) 2 times.
You can also see all the keyboard shortcuts in the jupyter notebook file 
by clicking on the help and then from dropdown on keyboard shortcuts.
