Using JupyterLab Effectively

What this module covers

By the end of it

• Navigate the JupyterLab interface: file browser, tabs, kernel indicator, and command palette
• Distinguish command mode from edit mode and switch fluently between them
• Use the twenty keyboard shortcuts that account for most day-to-day speed
• Explain how the kernel stores state, and why **execution order — not top-to-bottom
• Diagnose and prevent the hidden-state bug, the most dangerous behaviour in notebooks
• Apply magic commands: %timeit, %%time, %who, %run, %pip, %matplotlib
• Get help without leaving the notebook, using ?, ??, help(), and Tab completion
• Run shell commands from a cell with ! and capture their output into Python
