Jupyter notebook print all output

The Output widget can capture and display stdout, stderr and rich output generated by IPython. You can also append output directly to an output widget, or clear it programmatically.

After the widget is created, direct output to it using a context manager. You can print text to the output area:. Rich output can also be directed to the output area.

Anything which displays nicely in a Jupyter notebook will also display well in the Output widget. The status of this bug is tracked in this issue.

We can clear the output by either using IPython. With this set to Truethe widget contents are not cleared immediately. Instead, they are cleared the next time the widget receives something to display. Finally, we can use an output widget to capture all the output produced by a function using the capture decorator. Setting this to True will clear the output widget every time the function is invoked, so that you only see the output of the last invocation. Of course, you can also manually clear the output any time as well.

The output widget forms the basis of how interact and related methods are implemented. It can also be used by itself to create rich layouts with widgets and code output.

In the next example, we stack the controls vertically and then put the output of the function to the right. On some platforms, like JupyterLab, output generated by widget callbacks for instance, functions attached to the. Even on other platforms, it is unclear what cell this output should appear in. This can make debugging errors in callback functions more challenging.

You can then display the widget in a new cell to see the callback output. While using the. Typically, in larger applications, one might use the logging module to print information on the status of the program. However, in the case of widget applications, it is unclear where the logging output should go. A useful pattern is to create a custom handler that redirects logs to an output widget. The output widget can then be displayed in a new cell to monitor the application while it runs.

To see this directly, create a thread that repeatedly prints to standard out:. This always prints in the currently active cell, not the cell that started the background thread. This can lead to surprising behaviour in output widgets.

During the time in which output is captured by the output widget, any output generated in the notebook, regardless of thread, will go into the output widget. Jupyter Widgets latest. This goes into the output widget. HBox [ widgets. To see this directly, create a thread that repeatedly prints to standard out: import threading import time def run : for i in itertools.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Apparently this is possible in Mathematica, but not yet in Jupyter Notebook. The background comes from this: We're able to style Pandas Dataframes to show them just the way we need for our certification reports.

However, after that, there is no "pyplot. That's a big waste of the effort put into the pandas styler. Since Jupyter already allows you to export the entire notebook, is it possible to implement this on a per-cell basis as well, preferably only the cell output?

To clarify a little, what actually is the output you're seeing? I guess whatever the pyplot renderer provides? Could you provide an example notebook e.

For a pandas DataFrame, it's going to wind up calling df. Good point. Hang on while I fish out an example Take, for example this dataFrame with styled formatting:. If I display hs, I see the following nicely formatted table:.

Gone is the nice style sheet, the rendering of the LaTex labels, etc, I only see a shit table with some cruft at the top.

There seems to be no way of exporting the look of the table in the JP Notebook together with the table. Line 77 in fb4af However, what you mentioned might be implemented as a strategy to do just that if nbconvert is modified to allow the specification of output cells?

I don't think it even needs much modification of nbconvert: you could probably feed it a notebook with one cell which has one output, and use some recently added options to tell it to hide the input part of the cell. In theory one could use tags as an inverse from the current tag removal rules and only include those cells that are tagged. This would mean a new preprocessor, but that's not too much. Then it would be a matter of tagging the cells you want and exporting using an appropriate config file.It's possible to control which cells show up in your final book pages.

For example, you may want to display a complex visualization to illustrate an idea, but don't want the page to be cluttered with a large code cell that generated the viz.

In other cases, you may want to remove a code cell entirely. In both cases, Jupyter Books uses notebook cell tags to determine which code cells to hide. To make this process easier to manage, we recommend the JupyterLab Cell Tags extension.

If an element is hidden, Jupyter Book will display a small button to the right of the old location for the hidden element. If a user clicks the button, the element will be displayed. Note how we only see the output by default. Now try clicking the button to the right of the empty spot above! You can also hide the outputs of a cell. For example, if you'd like to ask users to think about what the output will look like first before viewing an answer. To do so, add the following tag to your cell:.

Finally, you can also hide markdown cells in your page.

This is useful if you'd like to provide some extra information to readers that want to dig deeper, but you don't want to clutter the page with too much information. To do so, add the following tag to your markdown cell:.

If you'd like to hide the whole cell both inputs and outputs just add each tag to the cell metadata, like so:. In the above examples, we are only hiding the inputs, with the option that readers can reveal them if they wish. However, if you'd like to completely remove the inputs, so that their contents do not make it into the book's HTML, you may use the following tag:.

The following cell demonstrates removing inputs.

Bartosz Mikulski

Note that in this case, there is no button available to show the input contents, the entire input cell is gone! You can also remove both the inputs and outputs of a cell, in which case it won't show up in your book at all. These cells remain in the notebook file itself, so they'll show up if readers click on a JupyterHub or Binder link from a page. Here's an example of cell metadata that would trigger the "remove cell" behavior:.In this short article, I am going to write Jupyter Notebook tips, extensions and hacks that I found useful when working with Jupyter Notebook.

For writing tips with Jupyter Notebook, please read this article. The gist is a simple way to share snippets hosted by Github. This hack allows you to create a gist from your codes in a Juptyer notebook cell. Assuming you have a Github account, first, you need to install gist. If you are using brew, please run the following in your terminal.

Now you need to login to Github. Put the following code in one of the cells in your Jupyter Notebook. You need to change myfile.

If you are printing out more than one item, display will display nicer outputs. If you feel too lazy to type print for all outputs, then this is for you. For Conda users, you need to add the following code in a cell. You need to restart Jupyter Notebook to make it work. You can use bash commands without! Try them out. Some examples you can use are:. Please install Nbextensions before using the following extensions. I use quite a few Nbextensions.

Please install Move Selected Cells by enabling it from the Nbextensions tab. This is super useful when you organize your cells. You might restart your Jupyter Notebook a couple of times to work. You can see Tabnine in action in the following gif images. What is your favorite? Do you have anything else to share?

Video on the topic: Jupyter Notebook tricks for advanced in The output of some cells can be huge or inappropriate and we may want to stop it or suppress it. You can do it in several different ways depending on your version, code and some other constraints:.

If you need to not show the output for several functions in Jupyter Notebook then you can use the next example. You need to call all functions and statements that you want to prevent from output with: with io.

Sometimes you want to do a quick check for a given functions - what and how many arguments you have or what is the signature for the given function. You have several different ways to achieve it.

You can continue to press again - Tab While you hold the Shift and more info will be shown. The other option to retrive information about functions and methods in IPython is by using: '? This can be done in a new cell by writing:?

Which will produce information for IPython and how to get help. In order to check the information for all magic functions you can write in a new cell and execute:. If you prefer to use dark themes with IPython Notebook you can very easily switch the main theme by installing: jupyterthemes :. Published a year ago 5 min read. By John D K. Alternatively you can get help by using? Within IPython you have various way to access help:? Or you can ask for a given function by:?

I'd like to be able to keep all my code for a project in a single notebook so when I share it all the needed code is there. If I do this the file can become very long and hard to understand.

Yes I saw that. I don't want to send people a notebook with javascript in it because I would be suspicious of receiving a notebook with javascript in it. If it is nonstandard I would rather not use it. Is code folding the same thing? I can't see how you can hide the entire code of a cell with it? I concur. This feature would be great for collaboration - you could view notebooks in 'presentation' mode, and write for such.

I have just now encountered this feature in an R notebook rendered as html, and it works beautifully. There is a button to the upper right of each cell that toggles between "hide" and "code". There is a similar button at the top of the entire notebook that has menu options for hiding or revealing code throughout the notebook. Well done--to be competitive, jupyter notebook badly needs this. I am still surprised that this feature is not available yet. At work I very often need to show reports to people.We love Jupyter notebooks for accommodating a computational narrative — a combination of explanation, code, and the output of this code.

Unfortunately, some tasks cannot be accomplished well by notebooks. If you are writing documentation for your software project, chances are that you want to provide navigation across many tutorials and explanation pages. You will also want to automatically document the API, perhaps also maintain a bibliography, and you certainly will want all the classes and functions from your module to automatically link to their documentation pages.

In short, your best bet is Sphinx. Sphinx does not provide a way to build a computational narrative: by itself, it cannot execute any code, nor does it know how to handle the output of that code.

We have just made an addition to this list, a freshly rewritten jupyter-sphinx extension, that was previously specialized to render Jupyter widgets. To embed arbitrary output in your documentation using jupyter-sphinx you only need to use the jupyter-execute directive:. Under the hood, all such code chunks are converted to cells in a notebook and executed using nbconvert. We then rely on the Jupyter format and protocol to interpret what to do with the results of executing the code.

This means you already know how the output will be shown: we apply exactly the same logic as Jupyter notebook does. For example, here we make a plot:.

And here we are rendering some widgets:. If you want to see jupyter-sphinx used to make package documentation, check out adaptivethe first adopter full disclosure—I am one of its authors.

An important corollary: building upon the Jupyter kernel protocol makes jupyter-sphinx language-agnostic; jupyter-sphinx works with absolutely any language for which a kernel exists. We would love to hear your feedback, especially if you are using other ways of embedding outputs in the documentation, or if you are using an older version of jupyter-sphinx.
