Edit Jupyter notebooks

You can apply various editing actions to one cell or to the entire notebook. Press the Ctrl+A once to select a cell at the caret and press Ctrl+A twice to select all cells in the notebook.

The editor for Jupyter notebooks has two modes: the edit mode and the command mode. Depending on the mode, you can either edit code in notebook cells or use keyboard shortcuts to perform specific actions with cells.

Edit mode

  • To toggle the edit mode, press Enter or click any cell.

  • When a cell is in the edit mode, it has a highlighted line with a caret inside the cell.

Command mode

  • To toggle the command mode, press Escape or click the gutter.

  • When in the command mode, you can navigate the notebook cell by cell using Up and Down keys, as well as use keyboard shortcuts to select, copy, paste, and delete cells.

Edit cells

  • A newly created notebook contains one code cell. You can change its type with the cell type selector in the notebook toolbar:

    Select a cell type
  • To edit a code cell, just click it.

  • To edit a Markdown cell, double-click it or press Enter and start typing. To preview the output, press Shift+Enter.

Work with notebook cells

Add cells

  • To add a code cell above the selected cell, do one of the following:

  • To add a code cell below the selected cell, do one of the following:

Select cells

  • To select a cell, click the gutter next to the cell.

  • To select several cells:

    • Click the gutter next to cells while holding Shift for a series of consecutive cells, or Ctrl for non-consecutive cells.

    • In command mode, hold Shift and press the Up and Down keys.

You can execute, copy, merge, expand, and delete the selected cells.

Copy and paste cells

  • To copy a cell in the command mode, press Ctrl+C, C, or click Copy cell on the notebook toolbar.

  • To paste the copied cell below, press Ctrl+V, V, or click Paste Below Cell.

  • To paste it above the current cell, press Shift with Ctrl+V/Shift+V.

  • You can also select the required action from the cell's context menu.

Split and merge cells

  • To merge a current cell with the cell below, right-click the cell and select the Merge Cell Below command from the context menu.

    Similarly, you can merge a cell above the selected cell with the corresponding command.

  • To merge several cells, select them, and then choose Cell | Merge Selected Cells from the main menu.

    Alternatively, you can use Find Action to run the Merge Selected Cells command.

  • To split a cell into two cells, place the caret in the line to break at, then right-click, and select the Split Cell from the context menu.

  3. Enter the tag and click Confirm.

To remove the tag, right-click it and select Remove Tag.

Use coding assistance

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

  • 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.

    Function completion
    Class variable completion
    Path completion
    Package completion
    DataFrame column name completion
  • Intention actions and quick fixes. You can add the missing imports by using the intention actions.
