What is the right way to debug in iPython notebook?

Question

As I know, %debug magic can do debug within one cell.

However, I have function calls across multiple cells.

For example,

In[1]:          


        

Answer 1

The %pdb magic command is good to use as well. Just say %pdb on and subsequently the pdb debugger will run on all exceptions, no matter how deep in the call stack. Very handy.

If you have a particular line that you want to debug, just raise an exception there (often you already are!) or use the %debug magic command that other folks have been suggesting.
