Teacher

This module is just a POC on how we could help newcomers better understand some exceptions.

This is just a POC, a full implementation is done by André Roberge at https://github.com/aroberge/friendly-traceback.

Demo

Importing teacher in an REPL or at the top of a file enable it, like:

import teacher

a = "Foo"
b = "Bar"

print(a * "bar")

Gives:

$ python test.py
test.py:6: TypeError: can't multiply sequence by non-int of type 'str'
You tried to multiply a by 'bar'
which is not allowed, the sequence a can only be multiplied by an integer.
