Programmatically replace input values in a notebook before running it
MIT License
This is a tool to run notebooks with input values. When you write the notebook, these are defined in the first code cell - or a cell with a 'parameters' cell tag - with regular assignments like this:
.. code-block:: python
stock = 'YHOO'
days_back = 600
Nbparameterise handles finding and extracting these parameters, and replacing them with input values. You can then run the notebook with the new values. This can be used for:
examples/batch.py
.examples/webapp.py
forNbparameterise can identify and replace numbers, strings, booleans (True/False), lists and dicts - the types which can be represented in JSON (apart from None). It's designed to change parameter values but keep their types, although this isn't enforced.
Extra information about the parameters, such as names to display in a user interface, can be stored in notebook metadata.
Nbparameterise is written in Python 3, but it can handle notebooks that use Python 2.
Usage:
.. code-block:: python
import nbclient
import nbformat
from nbparameterise import (
extract_parameters, replace_definitions, parameter_values
)
with open("Stock display.ipynb") as f:
nb = nbformat.read(f, as_version=4)
# Get a list of Parameter objects
orig_parameters = extract_parameters(nb)
# Update one or more parameters
params = parameter_values(orig_parameters, stock='GOOG')
# Make a notebook object with these definitions
new_nb = replace_definitions(nb, params)
# Execute the notebook with the new parameters
nbclient.execute(new_nb)

0.6.1
2024-05-15
- nbparameterise no longer requires `nbconvert <https://pypi.org/project/nbconvert/>`_,
and loads it only if you pass the deprecated ``execute=True`` option.
0.6
~~~
2023-02-28
- The parameters cell no longer needs to be the first code cell: if you add a cell tag
'parameters' to another cell, parameters will be extracted from and replaced in that
cell. Capitalisation doesn't matter. (`PR #27
<https://github.com/takluyver/nbparameterise/pull/27>`_).
- Only the parameter values are replaced: other code in the parameter cell will now be
preserved unchanged (`PR #19 <https://github.com/takluyver/nbparameterise/pull/19>`_).
The ``comment=`` parameter now has no effect, and it may be removed in a future
version.
- The ``execute=`` parameter for ``replace_definitions()`` is now deprecated.
Please use `nbclient <https://nbclient.readthedocs.io/en/latest/>`_ to execute
your notebook after substituting parameters.
- nbparameterise now requires Python 3.8 or above.
