I want to build an interactive story with Python to be printable and runable in both the windows terminal and the Spyder control. To adjust and justify the text I need the dimensions (mainly the width) of the console in character lines.
I have tried using os.get_terminal_size() but that only works for the windows terminal, not the Spyder console.
Syper version = 5.4.0
Python version = 3.9

I'm having trouble getting an ipython console in Spyder. It only offers a python interpreter under the "interpreters" menu.
I've seen this issue for a couple of others in Stackoverflow, but didn't have much joy with the proffered solutions.
I'm running linux Mint 16 and have installed both ipython (v 1.1.0) and Spyder (v 2.2.1) the easy way via the Mint Software Manager. I made sure that I also installed ipython-qtconsole and verified that I could run it from a terminal (i.e. ipython qtconsole).
I can activate an ipython console using the following commands in a Spyder python console:
import IPython
IPython.start_ipython()
though the font coloring is strange and doesn't work well on a white background (e.g. error messages in yellow and light green). It would be nice anyway to be able to start ipython the normal way from the Spyder menu.
You may want to install python-zmq for Python 2 and python3-zmq for Python 3.
I use Ubuntu 14.04, so:
sudo apt-get install python-zmq python3-zmq
I'm also using Linux Mint (18.1, at this time) and I have faced the same issue.
What solved this for me was installing Ipython3 Qt console (that, of course, should be Ipython Qt console if you're using Python 2.x).
In case you have it installed, check if you have the latest version
(In Linux Mint you can do this through Synaptic, aptitude or apt-get.)
I have just installed IPython 2.0 (April 2014) through Anaconda (64 bit) on a brand new pc with windows 7 (64 bit), performed the updates suggested and installed some packages with "$ conda install ".
I am loading IPython notebook with firefox and chrome. they are not the default browsers, so I used the information in this answer: https://stackoverflow.com/a/15748692/2344958
When I run IPython Notebook, it presents the landing pages and open new or imported notebooks, but it does not produce any output for cells.
I have no clue.
The only thing I can see is that the web console reports "Empty string passed to getElementById()."
Console works fine.
Any suggestion?
I found a page describing exactly the problem I had.
here the page:
Getting output with IPython Notebook
I actually have Sophos, but I have no control over it, and the solution that works so far was to start IPython with:
ipython notebook --ip=localhost
It also works by editing the line in configuration file
c.NotebookApp.ip = 'localhost'
I've installed Enthought Canopy 1.3.0.1715 on Max OSX 10.9.2, and updated all packages. All seems to have gone well until trying to create a new iPython notebook. When the notebook opens, none of the buttons for the notebook contain any images (just small 'x''s). II believe this problem is causing other issues in notebooks, but I'd like to get this one fixed first. Has anyone seen this and have a solution / idea? FYI, This works fine starting notebook from the terminal, just not as how Canopy is hosting the notebook.
I am experimenting with the music21 library, in preparation for a Machine Learning project that involves genre classification and categorization. I and following some tutorials available here. I am using MuseScore as my MusicXML program, and I am trying to run the whole thing from iPython.
Although I can run the some of the turtorials from the terminal, some elements don't seem to run well from inside iPython. For example:
In [3]: sBach.show()
Out[3]: <music21.ipython21.objects.IPythonPNGObject at 0x10da0aa10>
The line above shows that the PNG object is created, but not displayed. The expected output for 3 above is the following:
Experimenting with the following iPython command, I get a placeholder for an image, but not image.
In [6]: %load_ext music21.ipython21.ipExtension
In [7]: sBach.show()
I can't find any problem with my MusicXMLPath. This tutorial refers to the use of musc21 with Anaconda, but all my developments is done with Enthought, so I prefer not to run another virtual environment to use music21 with iPython.
Is there any way to run music21 in an Enthought/iPython notebook?
I have been grappling with this issue myself. ... Have you set your musicxmlPath in music21? If you have not, it's done via environment.set(key, value). You can query for available keys with environment.keys(). I hope this isn't too simple an answer, but it cleared up the problem for me.
This should be in the iPython music21 documentation somewhere, my apologies: iPython in music21 requires Lilypond to be installed for images to be generated within the notebook itself. There hasn't been (and won't be until MuseScore 2.0 is released) a way using MusicXML to generate PNG images of scores directly.
Edit: 2015 July; music21 2.0 w/ MuseScore 2 will generate the PNG images with MuseScore if it is installed and fallback to Lilypond if it is not installed.
If not yet tried, some steps to isolate the cause of the problem:
1) Update to the latest Canopy (Edit: currently 1.4.1) (might help this, will help generally, won't hurt).
2) Change the Pylab backend in Canopy's IPython shell to "Inline (SVG)", via Preferences / Python. (The default Qt backend in that shell conflicts with music21's use of the tkinter library.)
3) Test your script in that shell rather than in the notebook.
4) Ensure that Canopy User Python is your default Python in a Terminal window, as described here.
5) Test your scripts inside of plain ipython terminal (from Terminal, type ipython).
6) Test in ipython terminal in pylab mode (ipython qtconsole --pylab=inline).
7) Test your scripts inside of ipython notebook running in a regular browser (from Terminal, type ipython notebook, and/or ipython notebook --pylab=inline).
Had similar issues before. It's the same problem when people try to use plot function in ipython/jupyter notebook. You need to call
%matplotlib inline
For me the issue was solved by uninstalling the snap version of musescore and installing it from ppa:mscore-ubuntu/mscore3-stable via https://launchpad.net/~mscore-ubuntu/+archive/ubuntu/mscore3-stable
I've switched to Enthought's Canopy 1.0.0 but I miss the standalone QT shell and the QT notebook. I don't want to use the built-in shell which comes in the IDE. Where can I find the QT shell?
Are you asking about the IPython QtConsole? It and the Ipython notebook (NB this is not a QT notebook; it runs in a browser) are both accessible from the terminal / command prompt:
ipython qtconsole
ipython notebook
But you must have Canopy User Python on your PATH, as described here.
FWIW, the Python shell in Canopy is QtConsole, integrated with the editor and file browser.
