“Inner exception” (with traceback) in Python?

by

Python 3

In python 3 you can do the following:

try:
    raise MyExceptionToBeWrapped("I have twisted my ankle")

except MyExceptionToBeWrapped as e:

    raise MyWrapperException("I'm not in a good shape") from e

This will produce something like this:

   Traceback (most recent call last):
   ...
   MyExceptionToBeWrapped: ("I have twisted my ankle")

The above exception was the direct cause of the following exception:

   Traceback (most recent call last):
   ...
   MyWrapperException: ("I'm not in a good shape")
