within my code I use a Python package that calls external programs which write their output to the same console that IPython is running in. If I now run the same code from an IPython notebook, the output is not written to the notebook output cells, but into the console that the IPython notebook server is running in.
Do you know if it is possible to capture this output somehow, and then display it within the IPython notebook? I'm on Xubuntu 14.04, by the way.
Thank you very much for your help!
This gives you nice and comprehensive description of your problem and potential solutions. You need to try it out for yourself with your specific setup.

I'm new to VS Code. I wonder if VS Code has any panel to test run chunk of codes instead of creating a new file? I'm so used to traditional Rstudio, PyCharm, Jupyter Notebook IDE that I could just test out short chunks of code in the output command panel. However, it seems VS Code command output is just the terminal, which does not read my python code for the test running small chunks of code. Any suggestion on how to solve this?
Thanks,
Lily
You can create a jupyter notebook in the VSCode:
Or you can select Run Selection/Line in Interactive Window or Run Selection/Line in Python Terminal:
yes it does. vs code is such a great lightweight IDE.
https://code.visualstudio.com/docs/editor/debugging
You can make breakpoints or Logpoints and decide which part of the code you want to debug.
I think what you are looking for is jupyter notebook extension for vscode.
This is good guide to help you get started
I imagine this question is rather silly.
I'm using VS code and Jupyter notebooks within it. Is it possible to have the output sent to the interactive python interpreter instead/at the same time as the output beneath the Jupyter notebook cells? I tried searching, google but failed.
The answer in short is unfortunately 'no'. The Interactive window can be used with the #%% magic line or using the 'Jupiter.execSelectionInteractive' command (⇧ + ↩ on Mac). However, the later is not available in a notebook, only in .py files.
I have a Jupyter notebook that scrapes web data and saves a dataframe to a csv. I would like to run this every day automatically. I am using a mac for this project.
I have looked around a lot (including here: how to run a python jupyter notebook daily automatically), but as of yet I have not found a clear enough answer. I am quite new to all this, so I am looking for a step-by-step: like how you'd explain it to someone with no knowledge on cron etc.
Any advice would be much appreciated! Thank you!
Why don't you just convert the jupyter notebook into a raw python file? You can use this command: jupyter nbconvert --to script "[YOUR_NOTEBOOK].ipynb" (replace [YOUR_NOTEBOOK] with your notebook name)
EDIT: You could also use Juptext, as pointed out by #Wayne in the comments below.
If you need a jupyter notebook:
Use datalab or papermill
Use the SeekWall Chrome Extenstion
Create a custom python script to launch jupyter notebook, and run that python script using the Automator app in your Mac
I have already installed the code runner and Python extension for vscode. I also have installed Python 3.7 on my computer. It runs the code, but all it outputs is just this:
How can I fix this?
The print statement is going to print to terminal, I would change tabs from Output -> Terminal.
I have been using VS Code for Python development for the last month and really have not used OUTPUT.
A tool that I really LOVE is their Jupyter notebook support. With a comment of '#%%' you can create a cell to run that outputs similar to Jupyter notebook. Make sure you download the Python extension from Microsoft.
Example:
#%%
print('hello, world!')
Been using the safe and easy confines of PyCharm for a bit now, but I'm trying to get more familiar with using a text editor and the terminal together, so I've forced myself to start using iPython Notebook and Emacs. Aaaaand I have some really dumb questions.
after firing up ipython notebook from terminal with the command 'ipython notebook', it pops up on my browser and lets me code. but can i not use terminal while it's connected to ipython notebook server?
after writing my code in ipython notebook, i'm left with a something.ipynb file. How do I run this file from terminal? If it was a .py file, i know i could execute it by tying python something.py from the command line; but it doesn't work if i type python something.ipynb in the command line. And of course, I assume I hit Control-C to quit out of the running server in terminal first? or do I run the command without quitting that? Or am i doomed to test it in iPython and then copy and paste it to a different txt editor like Emacs and save it in a .py file to run it?
what good is the .ipynb file if i can't run it in terminal or outside the iPython Notebook browser? Could I get my code in a .py from iPython Notebook if I wanted to? (i assume I'll be able to easily run it in terminal by tying something.py then)
thanks in advance. I'm still very much trying to figure out how to use this thing and there aren't many answers out there for questions this elementary.
Yes, you can not use the same terminal. Solutions: open another terminal or run ipython notebook inside screen. If you use Windows you might want to take a look into this question
Notebook documents (ipynb files) can be converted to a range of static formats including LaTeX, HTML, PDF and Python. Read more about converting notebooks in manual
Notebooks are great, because you can show other people your interactive sessions accompanied with text, which may have rich formatting. And if someone can run notebook server he can easily reproduce your computations and maybe modify them. Check out awesome notebook on traveling salesperson problem by Peter Norvig as an example of what you can do with ipynb. Or this notebook. More examples are available here
You can run your IPython notebook process in background.
On Unix platforms you can perform that with (note the leading &):
ipython notebook &
Or after a "normal" run, hit [Control+z] and run the bg command
(some lecture).
you can convert .ipynb file into .py file using nbconvert
with Ipython notebook 2.x (some lecture):
ipython nbconvert --to python mynotebook.ipynb
with Ipython notebook 3.x (some lecture):
ipython nbconvert --to script mynotebook.ipynb
.ipynb contains your script AND results AND formatted text.
You can compare it to a literate script (but using "machine programming language").
