The jupyter notebook is a great tool for experimenting with python code and document it in one go.
A notebook consists of cells that have Code or Markdown text in it.
Keyboard shortcuts
First select a cell (click left from the editing area), then:
- <shift>j Select next cell too
- dd delete
- a paste a new empty cell above the current cell

To execute shell command start the cell with a !
E.g. to install a new module:

- Time a command with output
- time <commmand>
- Time a command running it 100000 times, no output
- %timeit <commmand>
