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
回答1:
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.

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.

I'm pretty sure you just have to do it manually. And you don't have to split code by putting it into different cells, in fact, I think its easy to not do that.
