Jupyter Notebook: command for hide the output of a cell?

In my notebook, I have a cell returning temp calculation results. It's a bit long, so after it is run, I want to hide it and when needed, to show it.

To do it manually, I can double click the left side of the output, to hide it

After double click

But is there any way I can do this by code? For example,

the last line of the cell, use a command like %%hide output, and the output would be hidden after finished running.

Additionally, can I get this feature in output HTML?

Add ; by the end of the cell to hide the output of that cell.

In the newer versions(5.0.0 at the time I'm writing this), pressing o in the command mode hides the output of the cell in focus. The same happens if you triple click in front of the output.

o is

• the first letter in the word "output" or
• lower case of 15th letter in the alphabet

You can add %%capture to the beginning of the cell.

Jupyter provides a magic cell command called %%capture that allows you to capture all of to outputs from that cell.

You can use it like this:

%%capture test print('test')

test.stdout => 'test\n'

In newer versions of Jupiter Notebook, select the desired cell, make sure you're in command mode and then on the menubar press Cell > Current Outputs. You have then three options:

• Toggle (press O in the command mode to apply the same effect)
• Toggle Scrolling (the default output)
• Clear (to clear the output all together)

Additionally, you can apply the same effect to all the cells in your document if you chose All Output instead of Current Output.
