I am working on my office computer, which due to security restriction do not allow me to install program (like miktex, ....). So i decided to export my notebook to .html.
As you can see the rendering is not good:
Some code is cutted
A lot of space is spoiled, there is large blank margin that i would like to see disapear completely, and i do not need the "IN[1]" in front of cell to allow the code to be more visible
How would you do to get an html whose printing display is good ?
I'm not sure if following steps meet your requirements.
(Open the terminal in the corresponding path and then execute the command)
Following command exports the .ipynb file to .html file, and by specifying args(TemplateExporter.exclude_input_prompt and TemplateExporter.exclude_out_prompt), the in[] and out[] is ommitted.
jupyter nbconvert --to html --TemplateExporter.exclude_input_prompt=True --TemplateExporter.exclude_output_prompt=True <your_file>.ipynb
TemplateExporter.exclude_input_prompt=True removes the in[] while TemplateExporter.exclude_output_prompt=True removes the out[] from the generated .html file.

I'm looking for a library/tool that can generate a .py file from a notebook, with the added feature that I want to control which cells (both code and markdown cells) get exported and/or excluded from the .py file. For example adding to cells something like %exclude or %include and have control at export time how to work with these tags. I found jupytext that may do this, but got me confused with the version control part / link of .ipynb/.md.
While working with ipython I used to edit an object with:
ed my_obj
And the editor opened the code defining the class of the object. I cannot find how to do the same thing in a jupyter notebook. Is it any possible?
The magic command %ed and %edit won't work in jupyter notebook.
I'm not quite sure why exactly jupyter doesn't support this edition, but probably because it can't know exactly when the user finished editing the file and the edited data should back to the cell.
If you want to edit the content of a string in a cell, you can use the following command:
a = 'jupyter'
get_ipython().set_next_input(a)
You can also use the %%writefile to save the content of the cell into a file and edit it outside jupyter.
%%writefile test.txt
[1, 2, 3]
And also use %load to bring the content to the cell:
%load test.txt
How is this done? I'd like to have the link be in a markdown cell.
For visual learners:
[blue_text](url_here)
In case it is not a markdown cell, that is with what I went:
from IPython.core.display import display, HTML
display(HTML("""text"""))
Just another tip, using magic expression.
%%html
Showing Text
Improved. Thanks to the comment of calocedrus.
Here is the code I use in my python notebook when I want to insert a link to a webpage inside a markdown cell (in a python notebook).
[Clickable_visible_hyperlink](Hidden_landing_URL)
--note Here is the clickable hyperlink, you can change the value
This might help too, if you're looking to display a link programmatically.
from IPython.display import display, Markdown
display(Markdown("[google](https://www.google.com)"))
I also tried
display(HTML("""<a href="https://www.google.com>google</a>"""))
But somehow I was getting the object printed out, instead of the rendered version.
For programming in R, do the following when using Jupyter Notebook or Jupyter Lab - (using the R kernel). These steps will display a web link and an image in a Notebook markdown cell. The following shows a real-life example of some study notes using Jupyter Lab and R.
First open a markdown cell in Jupyter - can be a new markdown cell or an existing markdown cell. Then copy and paste the actual web address into a markdown cell. This will provide an active link to that website from the Notebook.
Step 2, from that website, copy the image that you want to view in the Notebook. This image should be in a standard image format (.png, .jpg, etc ). Paste this image into the same folder on the computer where the Jupyter notebook file is located. Note: if the image is later deemed too large or small, then resize using any graphics software available - and then save the changed image into this same folder. Note: it is important to know the name of this image file.
Next, paste the name of the image file between the quotation marks in the following code: . If this file in not within your existing jupyter notebook working directory, then a path to the image file will need to be placed inside the quotation marks.
Step 3, also included is an example of the line of code (also used in Notebook markdown cell) to create colored text in markdown cells. In this line of code, the double ## character results in the second largest font being used in Jupyter. Smaller text using more of these characters - with #### being the smallest. One # results in the largest font output.
Last, be sure to close and run the markdown cell to view the output. The code for the markdown cell follows, and further below shows the output from the Notebook.
Code in Markdown cell:
"https://www.tensorflow.org/images/colab_logo_32px.png" # link to website
<img src="tidyflow.png" /> # The image file (This path is the same folder as Notebook file)
## <font color = cyan> Some Colored Text in Notebook Markdown Cell </font> # colored text
Output:
I mistakenly printed to much to the output during a single cell's execution and now the browser tab completely freezes every time that notebook is opened. I tried restarting ipython and it didn't help (I am guessing that each time it is loaded, also all the chunk of text is loaded with it).
Is there a way to load a notebook with outputs suspended or clear?
One hack if you're desperate: open the .ipynb file, which is a text file. Scroll down to the lengthy cell output and delete it. Of course, you need to be careful that the result is still a valid .ipynb file.
nbstripout is a simple tool that removes all output from a notebook (without needing to open the notebook in your browser).
your code will be saved in the form of JSON. open it with json viewer and carefully delete the unwanted output cell and save it back.
I want a whole file as a text file instead of just a cell in IPython notebook.
I write some codes in IPython notebook and now I want to test them ,so I tried to upload some text file into IPython notebook as the raw data.But the files' extension are always ".ipynb" and the format of the text files have changed so my code can't read it correctly.
How could I upload a text file into Ipython notebook? thanks in advance
Can you be more elaborate?
Are you trying to read data out of the text file? In that case regular python open and read functions can get you the data into variables. You can even do Unix "cat" the contents of the file in a variable:
var=!cat file
Or are you trying to get the text in the ipynb files as content in an input cell so you can edit them and run them? The ipynb files are usually created by the notebook engine and they are JSON formatted. So if you just copy paste the text from them into a cell, they won't be usable as is. Use some JSON parsing to interpret their content. They are not regular python code so "%run file" wont work to get their code executed by ipython.
Elaborating the use cases may help others to give solutions...
The following lines open a text file and display the content in a jupyter notebook cell.
text_file = open(full/path/to/text/file)
file_content = text_file.read()
print(file_content)
text_file.close()
I hope this helps.
It may be late, you can do this
%%pycat full/path/to/text/file
