Windows ipython qtconsole

You can plot with matplotlib in IPython, or the plotting library of choice in your kernel. The widget also exposes the ability to print directly, via the default print shortcut or context menu. Note that syntax highlighting does not survive export.

This is a known issue, and is being investigated. Terminal IPython has always had some coloring, but never syntax highlighting. The Qt widget, however, has full syntax highlighting as you type, handled by the pygments library. The style argument exposes access to any style by name that can be found by pygments, and there are several already installed. Calling jupyter qtconsole -h will show all the style names that pygments can find on your system.

You can also pass the filename of a custom CSS stylesheet, if you want to do your own coloring, via the stylesheet argument.

The default LightBG stylesheet:. The Qt console is configurable via the ConsoleWidget. For instance, to use 9pt Anonymous Pro:. With the two-process ZMQ model, the frontend does not block input during execution. This means that actions can be taken by the frontend while the Kernel is executing, or even after it crashes. This can be done in the middle of a blocking execution.

The frontend can also know, via a heartbeat mechanism, that the kernel has died. This means that the frontend can safely restart the kernel. Since the Kernel listens on the network, multiple frontends can connect to it. These do not have to all be qt frontends - any Jupyter frontend can connect and run code. Other frontends can connect to your kernel, and share in the execution.

This is great for collaboration. The --existing flag means connect to a kernel that already exists. Starting other consoles with that flag will not try to start their own kernel, but rather connect to yours. By default, this file will be in your Jupyter runtime directory. If it is somewhere else, you will need to use the full path of the connection file, rather than just its filename.

You are giving any computer that can see you on the network the ability to connect to your kernel, and view your traffic. Read the rest of this section before listening on external ports or running a kernel on a shared machine. By default for security reasons , the kernel only listens on localhost, so you can only connect multiple frontends to the kernel from your local machine.

You can specify to listen on an external interface by specifying the ip argument:. If you specify the ip as 0. Messages are not encrypted, so users with access to the ports your kernel is using will be able to see any output of the kernel. They will NOT be able to issue shell commands as you due to message signatures.

If you disable message signatures, then any user with access to the ports your kernel is listening on can issue arbitrary code as you. DO NOT disable message signatures unless you have a lot of trust in your environment.

The one security feature Jupyter does provide is protection from unauthorized execution. This was tested on Ubuntu Seanny Seanny 6 6 silver badges 15 15 bronze badges.
