Edit Jupyter notebook files

Set up your project

1. In PyCharm, create a new Python project.

2. Install the jupyter package for the selected interpreter.

3. When all the indexing processes are finished, you are ready to start working with the notebook files.

Create a notebook file

1. Do one of the following:

   • Right-click the target directory in the Project tool window, and select New from the context menu.

   • Press Alt+Insert

2. Select Jupyter Notebook.

3. In the dialog that opens, type a filename.

A notebook document has the *.ipynb extension and is marked with the corresponding icon.

Add cells

• 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 the Cell menu.

  

• 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.

Use code assistance

You can edit code cells with the help of Python code insights, such as syntax highlighting, code completion, and so on.

• PyCharm enables code completion for the names of classes, functions, and variables. Start typing the name of the code construct, and the suggestion list appears.

  Methods and functions

  Class variables

  File paths

  Packages

  DataFrame columns

  

  

  

  

  note

  The auto-completion of DataFrame columns names is available in runtime. PyCharm will suggest the names for columns only if the cell where the DataFrame is created has already run in the current kernel session.

  

• 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.

Cell selection

• 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 or click on the notebook toolbar.

• To paste the copied cell below, press Ctrl+V or click . 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 select Merge Cell Below command 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 the Split Cell from the context menu.

Delete cells

• To delete a selected cell, do one of the following:

  • Click on the notebook editor toolbar.

  • Right-click the cell and select Delete Cell from the context menu.
