== Why is this an issue?

An `except` clause that only rethrows the caught exception has the same effect as omitting the `except` altogether and letting it bubble up automatically. 

[source,python]
----
a = {}
try:
    a[5]
except KeyError:
    raise  # Noncompliant
----

Such clauses should either be removed or populated with the appropriate logic.

[source,python]
----
a = {}
try:
    a[5]
except KeyError as e:
    logging.exception('error while accessing the dict')
    raise e
