%%python prints traceback, no exception name or value

See original GitHub issue
def foo(x, y):
    return x / y

foo(1, 0)

in a metakernel_bash notebook shows a traceback, but doesn’t include the exception name and value:

  File "/Users/parente/miniconda3/envs/spylon-kernel-dev/lib/python3.6/site-packages/metakernel/magics/", line 25, in exec_code
    exec(code, globals())

  File "<string>", line 4, in <module>

  File "<string>", line 2, in foo

I know the exception name and description are available because running the function that does the exec for the python magic like so:

from metakernel.magics import python_magic
z = python_magic.exec_code('''
def foo(x, y):
    return x / y
foo(1, 0)
''', globals(), None)

print(z.ename) # 'ZeroDivisionError'
print(z.evalue) # ('division by zero',)

shows the ename and evalue attributes include the additional information that is missing from the magic’s default output of the traceback alone.
