I would like to get the time spent on the cell execution in addition to the original output from cell.
To this end, I tried %%timeit -r1 -n1 but it does
%%timeit -r1 -n1
You can use timeit magic function for that.
timeit
%timeit CODE_LINE
Or on the cell
%%timeit SOME_CELL_CODE
Check more IPython magic functions at https://nbviewer.jupyter.org/github/ipython/ipython/blob/1.x/examples/notebooks/Cell%20Magics.ipynb
