The print statement/function happily accepts multiple arguments, and
will join them according to a set of predefined rules. The logging
functions don't have those rules, so they take one message and some
optional parameters. Try this, instead:

logging.info("%r %r %r", out, err, ret)

and then tweak the format string according to requirements. For a
quick dump, this will serve you well.
