PDB:
Currently I've set my environment () to include ['pythonbreakpoint'], and set it to 'pdb.set_trace'. I even added...
**_from IPython.display import clear_output
import pdb;
import sys;
from IPython import embed
import os
os.environ['PYTHONBREAKPOINT'] = 'pdb.set_trace'

DEBUGGING environment variables for kevin...

print(os.getenv('PYTHONBREAKPOINT'))_**
... and that failed to execute breakpoint() in my script! I also consulted python.org (https://docs.python.org/3/search.html?q=breakpoint%28%29)!
Just to be clear on how to 'supposedly' use this 'feature'! To no avail, the script executes past the breakpoint() statement in my (.ipynb) file.
