JupyterLab & Jupyter Notebook Cheat Sheet Commands


Are you starting to create machine learning models (using python programming) using JupyterLab or Jupyter Notebook? This post list down some commands which are found to be very useful while one (beginner data scientist) is getting started with using JupyterLab notebook for building machine learning models.

  • Notebook Operations: The following command helps to perform operations with the notebook.
    • Ctrl + S: Save the notebook
    • Ctrl + Q: Close the notebook
    • Enter: While on any cell, you want to enter edit mode, press Enter.
  • Cells Operation: The following commands help with performing operations on cells:
    • J: Select the cell below the current cell; This command would be used to go through cells below the current cell; Once you reached to the desired cell, you could Shift + Enter to execute the command in the given cell.
    • K: Select the cell above the current cell
    • X: Cut the content of the current cell

    • D,D: Delete the cell
  • Notes taking operations using Markdown editor: If you are a blogger, you would love these shortcuts. Very useful for taking notes while you are working on your models.
