Edit Jupyter notebook files
Set up your project
To open an existing .ipynb file, follow the same steps as for the files of the other types. If needed, you can create a notebook file.
Create a notebook file
Do one of the following:
Right-click the target directory in the Project tool window, and select New from the context menu.
Select Jupyter Notebook.
In the dialog that opens, type a filename.
A notebook document has the *.ipynb extension and is marked with the corresponding icon: .
A newly created notebook contains one code cell. You can change its type with the cell type selector in the notebook toolbar:
Add more code or Markdown cells to your notebook. You can add a code cell after the very last cell, add a code cell or Markdown cell right after the selected cell, and insert a new cell after executing the selected cell. You can find these actions in themenu.
To edit a code cell, just click it.
To edit a Markdown cell, double-click it and start typing. To preview the output, press Shift + Enter.
You can apply various editing actions to one cell or to the entire notebook. Press the Ctrl+A once to select a cell at caret, and press Ctrl+A twice to select all cells in the notebook.
When editing notebook files, mind that IntelliJ IDEA updates the source code and preview of the notebook if it has been changed externally.
Use code assistance
You can edit code cells with the help of Python code insights, such as syntax highlighting, code completion, and so on.
IntelliJ IDEA enables code completion for the names of classes, functions, and variables. Start typing the name of the code construct, and the suggestion list appears.
Intention actions and quick fixes. You can add the missing imports on-the-fly by using the intention actions.
Note that you can add an import statement to the current cell or to the first cell of the notebook.
To select several cells in the command mode, press Shift and Up/ Down keys.
Copy and paste cells
To copy a cell in a command mode, press Ctrl+C.
To paste the copied cell below, press Ctrl+V. To paste it above the current cell, press Shift with Ctrl+V
Split and merge cells
To merge a current cell with the cell below, right-click the cell and selectcommand from the context menu.
Similarly, you can merge a cell above the selected cell with the corresponding command.
To split a cell into two cells, set the cursor on the line to break at, then right-click, and select thefrom the context menu.
To delete a selected cell, do one of the following:
Click on the notebook editor toolbar.
Right-click the cell and selectfrom the context menu.
To compare any two notebooks, select one in the Project tool window, right-click it, and select from the context menu (Ctrl+D).
In the file system, select a notebook you want to compare to.
IntelliJ IDEA shows two notebooks and the comparison results in the diff viewer:
You can modify each of the compared notebooks by using the buttons: and . You can also edit the notebooks directly in the diff viewer. Once the change is applied, IntelliJ IDEA saves it.
