Code Consoles

Code consoles allow you to run code interactively in a kernel. The cells of a code console show the order in which code was executed in the kernel, as opposed to the explicit ordering of cells in a notebook document. Code consoles also display rich output, just like notebook cells.

Create a new code console by clicking the + button in the file browser and selecting the kernel:

Clear the cells of the code console without restarting the kernel by right-clicking on the code console and selecting “Clear Console Cells”:
