xeus-python is a Jupyter kernel for Python based on the native implementation of the Jupyter protocol xeus.
Launch the Jupyter notebook with jupyter notebook or Jupyter lab with jupyter lab and launch a new Python notebook by selecting the xpython kernel.

xeus-python has been packaged for the conda package manager.
To ensure that the installation works, it is preferable to install xeus-python in a fresh conda environment. It is also needed to use a miniconda installation because with the full anaconda you may have a conflict with the zeromq library which is already installed in the anaconda distribution.
The safest usage is to create an environment named xeus-python with your miniconda installation
conda create -n xeus-python
conda activate xeus-python # Or `source activate xeus-python` for conda < 4.6Then you can install in this environment xeus-python and its dependencies
conda install xeus-python notebook -c conda-forgeOr you can install it from the sources, you will first need to install dependencies
conda install cmake xeus nlohmann_json cppzmq xtl pybind11 jedi pygments notebook -c conda-forgeThen you can compile the sources
cmake -D CMAKE_PREFIX_PATH=your_conda_path -D CMAKE_INSTALL_PREFIX=your_conda_path -D PYTHON_EXECUTABLE=`which python`
make && make installTo try out xeus-python interactively in your web browser, just click on the binder link:

Check-out this blog post for the answer: https://blog.jupyter.org/a-new-python-kernel-for-jupyter-fcdf211e30a8. Long story short: xeus-python does not cover 100% of the features of ipykernel. For examples, IPython magics are not supported yet by xeus-python. However:
- xeus-python is a lot lighter than ipykernel and IPython combined, which makes it a lot easier to implement new features on top of it. Our next goal is to augment the protocol to implement a Python debugger in JupyterLab.
- xeus-based kernels are more versatile in that one can overload e.g. the concurrency model. This is something that Kitware’s SlicerJupyter project takes advantage of to integrate with the Qt event loop of their Qt-based desktop application.
