Ipython Notebook: Elegant way of turning off part of cells?

Question

In my ipython notebook, there is part of cells that serves as preliminary inspection.

Now I want to turn it off, since after running it I know the status of the dataset, but I also want to keep it, so other people using this notebook can have this functionality.

How can I do it? Is there any example of doing it?

1. I can comment out these cells, but then switching between on and off would be quite laborious. And may not be quite convinent for other people.

2. I can abstract it into a function, but that itself has some methods, so the code would be quite convoluted, and may be hard to read?

Answer 1

Using Jupyter notebook you can click on a cell, press esc and then r. That converts it to a "raw" cell. Similar thing can be done to convert it back, esc + y. No comments needed, just key presses.

Within Juptyer notebook, go to Help -> Keyboard shortcuts for more.

Here's a snippet:

Command Mode (press Esc to enable)

• ↩ : enter edit mode

• ⇧↩ : run cell, select below

• ⌃↩ : run cell

• ⌥↩ : run cell, insert below

• y : to code

• m : to markdown

• r : to raw

Answer 2

在Jupyter中，一个人可以使用

%%script false

作为单元格开头的魔术前导，以避免其执行。

Answer 3

您可以使用一个条件，但需要额外缩进一个。

cellEnabled = 0
#cellEnabled = 1

if cellEnabled:
    doA()
    doB()
