Also in do_retval. And the exception is silently ignored in do_p and do_pp when
repr() fails, which is not correct.
A solution could be to have a message_safe method to be used in such cases. For
example, substitute in do_args:
self.message('%s = %r' % (name, dict[name]))
with:
self.message_safe('%s = %r', name, dict[name])
def message_safe(self, fmt, *args):
try:
print(fmt % args, file=self.stdout)
except Exception:
exc_info = sys.exc_info()[:2]
self.error(traceback.format_exception_only(*exc_info)[-1].strip())
