PR Description

The from keyword sets the __cause__ attribute of the exception, which stores the "cause" of the exception. The availability of an exception "cause" is useful for debugging.

When you raise a new exception after another exception was caught it's likely that the second exception is a friendly re-wrapping of the first exception. In such cases raise from provides a better link between the two tracebacks in the final error.
