Jupyter

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.

• a paste a new empty cell above the current cell
• b paste a new empty cell below the current cell
• y change cell type to code
• m change cell type to Markdown
• c copy cell
• v paste copied cell below current cell
• h show help

Other tricks

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>
