In other words, quit() seems to only stop the execution of the cell itself, not the whole script.

Is there some way to add a breakpoint to your code so that it stops executing when it gets to it?

As far as I know, jupyter notebook doesn't have a breakpoint function however you can add something like:

assert False, "breakpoint"

where you want to stop although it isn't very elegant.

The Visual Python Debugger for Jupyter Notebooks You've Always , As far as I know, jupyter notebook doesn't have a breakpoint function however you can add something like: assert False, "breakpoint". def add_to_life_universe_everything (x): answer = 42 # we want a breakpoint here answer += x return answer add_to_life_universe_everything (12) pdb. The built-in Python debugger pdb works just fine in a Jupyter notebook. With import pdb; pdb.set_trace() we can enter the debugger and get a little interactive prompt.

You can use IPython.core.debugger.Pdb to invoke pdb. Insert the following line to set a breakpoint.

from IPython.core.debugger import Pdb; Pdb().set_trace()

See this page for debugger commands.

Also, you can use %debug magic to invoke pdb after an error. Just type %debug to the next cell if an exception occurs. Then pdb runs from its stack frames.

Jupyter Notebooks are best known as tools for Data Scientists to display Python, Spark or R scripts. A Jupyter Notebook enables you to share words, images, code AND code results. .NET interactive Jupyter notebooks add c sharp, f sharp and PowerShell core to the mix.

Here’s how to debug your code when using a Jupyter/iPython notebook. Use Tracer()(). Here’s an example using a simple function (based on this lucid explanation). def test_debug(y): x = 10 # One-liner to start the debugger here. from IPython.core.debugger import Tracer; Tracer()() x = x + y for i in range(10): x = x+i return … Continue reading "How to debug a Jupyter/iPython notebook"

  • Does this answer your question? What is the right way to debug in iPython notebook?
  • I simply use 0/0 which throws a ZeroDivisionError and stops the execution
  • That does exactly the same as using quit() as far as I can tell. In other words it doesn't stop the rest of the script from running.
