Jupyter notebook support
With Jupyter Notebook integration available in PyCharm , you can easily edit, execute, and debug notebook source code and examine execution outputs including stream data, images, and other media. 
Notebook support in PyCharm includes:
Editing and preview:
Ability to present a notebook as source code with textual cell definitions and manipulate cells as regular code.
Live preview of the cell execution output and Markdown content.
Auto-saving changes that you make in your files. Saving is triggered by various events, for example, closing a file or a project, or quitting the IDE.
Coding assistance:
Error and syntax highlighting.
Ability to create line comments Ctrl+/.
Ability to run cells and preview execution results.
Dedicated Jupyter Notebook Debugger.
Shortcuts for basic operations with Jupyter notebooks.
Ability to recognize .ipynb files and mark them with the
icon.
Quick start with the Jupyter notebook in PyCharm
To start working with Jupyter notebooks in PyCharm:
Create a new Python project, specify a virtual environment, and install the jupyter package.
Open or create an .ipynb file.
Add and edit source cells.
Execute any of the code cells to launch the Jupyter server.
Analyze execution results in the Preview pane.
Get familiar with the user interface
Mind the following user interface features when working with Jupyter notebooks in PyCharm.
Notebook editor
In PyCharm, you can work with Jupyter notebook files using three viewing modes:
In this mode, you can add notebook cells and edit them.
In this mode, you can both edit cells and preview their output. This is the default viewing mode for Jupyter notebooks in PyCharm.
In this mode, you can preview markdown and raw cells as well as code cell execution results.
Editing and preview modes reflect the currently selected PyCharm user interface appearance.

| Select this checkbox to allow executing JavaScript in your Jupyter notebook. |
| You can preview the notebook in a browser. |
| Enables auto scrolling from the source cell in the Editor to the corresponding output in the Preview pane. |

Tool windows
The Server Log tab of the Jupyter tool window appears when you have any of the Jupyter server launched. The Server log tab of this window shows the current state of the Jupyter server and the link to the notebook in a browser.
It also provides controls to stop the running server (
) and launch the stopped server (
).
The Jupyter Variables tool window the detailed report about variable values of the executed cell.
You can use the 
icon to manage the variables loading policy.
