The notebook editor provides an Analysis pane to browse and add the code snippets for the analysis tools available in your ArcGIS Online organization. The standard feature analysis tools are always available in the pane. To access the pane, click Analysis on the top ribbon of the notebook editor.
Adding a tool to your notebook inserts the ArcGIS API for Python syntax for that tool into a new cell.
Explore the Analysis pane
When you open the Analysis pane, each available toolset appears as a tab. On each tab, the tools are grouped into categories, identical to how they appear in your ArcGIS Online organization.
To view the tools in a category, expand or collapse it using the button next to the category. Click the Info button for a category or a tool to view its details. When you locate the analysis tool you want to use, click the Add button 
to add the Python code snippet corresponding to the tool into a new cell in your notebook.
Feature analysis tools
Feature analysis tools can be used to perform common analytical functions such as finding hot spots, locating streets and addresses, finding a place, routing, or accessing a geodatabase. By performing analysis, you can answer questions and make decisions using more than visual analysis.
Raster analysis tools
The raster analysis tools are used to analyze and process imagery and raster datasets, such as multispectral satellite and aerial imagery, elevation, and scientific datasets. The tools can analyze imagery based on algorithms, and analyze spatial patterns, analyze terrain to derive surfaces, and summarize and manage data. You can create and run spatial analysis models and image processing chains while using distributed processing and storage. These tools manage and perform scalable raster analysis and image processing on large volumes of raster data from multiple sources.
