What is the proper way to reset the cell number in a notebook cell? When I evaluate all the cells of a notebook I want to always start with the number In[1] as the first cell label of the notebook in order to have a predictable number of all the subsequent cells, something like kill(labels) in Maxima.
In Jupyter, the number on the left are not the number of the cells but the order in the execution. IPython has the very same behavior
$ sage -ipython

In [1]: 1+1
Out[1]: 2
In [2]: 3+5
Out[2]: 8

But in a console as above, you are not allowed to edit the input lines as you would do with cells in a notebook.
The proper way to reinitialize the execution of the kernel (and hence starting again from 1) is to do Kernel -> Restart.
What I want is a command in a Sage Notebook cell that will make the next cell executed to be In[1]
First of all, I assume that you are using the Jupyter notebook since the legacy Sage notebook does not have any numbering for its cell (at least that are visible). As I wrote at the end of my answer you should use Kernel -> Restart.
