Python3.6

I've installed a Python3.6 kernel and am the notebook is having trouble with the new f string formatting. The code runs correctly but the highlighting shows every character remaining in the cell after the open quote as part of the string, after the close quote, all remaining lines, etc..

That will likely require codemirror syntax highlighting to be updated,
waiting for a new codemirror release and update the codemirror used by
Jupyter.

Highlighting is still known to be off in many editors, my guess is
that type annotation will be wrong as well.

Cheers,

In conda Py 3.6 install, syntax highlighting seems to be in order.

I installed Conda and it still was not working. I'm running Ubuntu 16.04 and the problem persists in Firefox and Chrome.

Can you post a screenshot of messed up syntax highlighting? I'm on Xubuntu 14.04.5 and using google-chrome-beta from Google repo.

This has been fixed in https://github.com/jupyter/notebook/pull/1764, so you need notebook server version 4.3 or above to have it. And make sure the files are not cached.

See the `Help > About` Menu in the notebook to see the version. If you can't upgrade we can figure out how to hack our way around that and monkeypatch the javascript.

And if by "files cached" you are referring to the notebook itself, my example was a new notebook.

The problem also occurs under conda with a clean cache.

I think that Matthias meant that you should make sure to rebuild the json (if using an editable install) and to clear your browser's cache.

This is the bash_history of a new Ubuntu 16.04 virtual machine I created to see if I had a problem with conflicting files.

Unfortunately, I have been able to replicate the issue in a new Ubuntu 16.04 virtual machine with a fresh install.

I found the problem. If I start the notebook from the command line within and active Conda instance I get version 4.2.3 of the notebook server. If I start it any other way I get Python 3.6 but using version 4.2.1 of the notebook server.

I'm going to guess conda is not completely yet up-to date with the holidays.
And conda-forge does not have python 3.6 in stable channels yet.

let's give maintainers a couple of days to update stuff, and give
users change to submit PRs to get involved :-)

The f-string problem is back. I had it working using both Conda and Virtualenv but after recent updates f-strings are neither highlighted nor edited correctly. I tried creating two new virtual machines with fresh installs of Ubuntu 16.04 and after updating and installing either Anaconda or using Virtualenv I wound up with the resulting highlighting problems.

Hi Damon,

Unfortunately, we reverted to an older version of Codemirror to deal with some issues on Safari, and that meant we lost the Python 3.6 syntax highlighting fixes. We've updated it again in master with a patch to fix the Safari problem, so it should be back in order for 5.0.

Thomas,

What was the working version of Codemirror? I would like to experiment with manually replacing it, in a virtual environment, to get the highlighting back. I want to try this because it seems that version 5.0 will only be in beta next month and I've already been writing 3.6 code.

Never mind. I installed notebook version 4.3 and it's working again. Thanks for letting me know what happened and again thanks to everyone working on Jupyter for all the hard work.

We found a fix for CodeMirror, and are planning to release 4.3.2 with just this patch shortly.

The most recent version of CodeMirror is 5.23.0.
