iWut

Friendlier tracebacks, collapsing frames with library code, inline variable values, and adding context.

Installation

pip install iwut

Notebook

%load_ext iwut

Global Usage: You can turn on wut globally to catch and re-render all tracebacks.

%wut on

You can likewise turn off wut with %wut off.

Case-by-case Usage: Once you hit an error, you can use wut to retroactively re-parse the exception. For example, you may have the following

> 1/0
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
/tmp/ipykernel_165/2354412189.py in <module>
----> 1 1/0

ZeroDivisionError: division by zero

In the next cell, simply use the line magic

%wut

This will pretty print a friendlier traceback. You can alternatively, prepend the cell magic on a faulty cell, like this:

%%wut
1 / 0
