Use Ctrl+Backspace or Ctrl+Delete both will delete blank lines.
Ctrl+Backspace can be used to delete whole text of line before cursor position.
Similarly Ctrl+Delete to delete text after cursor.

I think the question is about deleting an empty new line of a cell.My solution is to write something in the line you want to delete, then go to the end of the line above it and press delete till the junk written in the line to be deleted is cleared.This deletes the empty new line as well.

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. <a href="https://github.com/ipython/ipython/wiki/Dev:-Coding-style" rel="noreferrer">https://github.com/ipython/ipython/wiki/Dev:-Coding-style</a>

有没有一种从IPython笔记本中删除空白行的简单方法？我已经养成了在网页开发中使用空行的习惯，我的手指往往会自动按回车。这使得IPython笔记本减少了(因为占用了我14英寸的屏幕太多)，在大多数情况下，它的可读性不高。我想知道是否有一种自动从笔记本中删除空行的方法。在笔记本中，我认为拆分代码的首选方法是将每个单独的方法放置到不同的单元格中。是普遍接受的笔记本样式指南，还是PEP 8适用于实际情
