Jupyter / IPython Usage

$pipinstallcallgraph

In a Jupyter IPython notebook:

%load_extcallgraphdefnchoosek(n,k):ifk==0:return1ifn==k:return1returnnchoosek(n-1,k-1)+nchoosek(n-1,k)%callgraphnchoosek(4,2)

As an alternative to including%load_ext callgraph in each notebook thatuses%callgraph, you can add the extension to the Notebookconfiguration file in your IPython profile.

Your configuration file is probably called~/.ipython/profile_default/ipython_config.py.(You can runipython profile locate to find it.)Edit this file to include the following line:

c.InteractiveShellApp.extensions = ["callgraph.extension"]

(If your configuration file already includes an uncommented statementc.InteractiveShellApp.extensions = […], edit the list of extensions inthat line to include"callgraph.extension".

Seeextension example notebook for additional examples.
