execute a Jupyter Notebook cell programmatically

问题

Is it possible for a Jupyter Notebook cell to execute another cell programmatically? (i.e. using Python)

And if so, is it possible to specify the cell number to execute?

回答1:

There is a javascript function called execute_cells that when given an list of cell indices runs those cells.

%%javascript
Jupyter.notebook.execute_cells([0]) # 0 to run first cell in notebook etc.

If you need to run it specifically in a Python code cell, one can use the Javascript function in the IPython.display module to execute javascript

from IPython.display import Javascript
Javascript("Jupyter.notebook.execute_cells([2])")
