How do I debug a Python script in a Jupyter notebook?

The easiest way to debug a Jupyter notebook is to use the %debug magic command. Whenever you encounter an error or exception, just open a new notebook cell, type %debug and run the cell. This will open a command line where you can test your code and inspect all variables right up to the line that threw the error.

How do I debug in IPython?

IPython has another way to start a debugger. You don’t need to modify the source code of any file as we did before. If you run the %run -d magic command, IPython will execute the file and put a breakpoint on the first line there. It’s just as if you would put the import ipdb; ipdb.
