Package that provides Jupyter kernels for use with the consoles of Spyder, the Scientific Python Development Environment.

These kernels can launched either through Spyder itself or in an independent Python session, and allow for interactive or file-based execution of Python code inside Spyder.

To learn about creating, connecting to and using these kernels with the Spyder console, please read our [documentation](https://docs.spyder-ide.org/current/panes/ipythonconsole.html).
