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.
