Attachments: Presents a list of attachments for the current cell. For example, you can add images or pictures to markdown cells.
Tags: Manages tags associated with each cell. A tag is a piece of information that you provide that helps you understand and classify the cell. The tags are for your use; they mean nothing to Notebook. When you use tags correctly, they enable you to interact with cells in new ways, but you must use the tags consistently to allow tags to work properly.
Interacting with the Kernel
The kernel is the server that enables you to run cells within Notebook. You typically see the kernel commands in a separate command or terminal window, such as the one shown in Figure 5-5.
FIGURE 5-5: The kernel displays its commands in a separate Jupyter Notebook window.
Each entry shows the time the kernel executed the task, which application the command executed, the task it performed, and any resources affected. In most cases, you don’t need to do anything with this window, but viewing it can be helpful when you run into problems because you often see error messages that can help you resolve an issue.
