TypeError: not all arguments converted during string formatting

[Ganesh Pal]

Hi Team,


Iam on python 2.6 and Linux , I had replaced print out, err ret with
logging.info(out, err ,ret) in the below code . I am getting

"TypeError: not all arguments converted during string formatting"
error any quick suggestion


try:
out, err, ret = run(cmd, timeout=60)
# New line added below
logging.info(out, err ,ret)
if ret != 0:
logging.error("Can't run %s got %s (%d)!" % (cmd, err, ret))
raise Exception("Preparing cluster failed...Exiting !!!")
except Exception as e:
logging.exception("Failed to run %s got %s" % (cmd, e))
sys.exit("Preparing cluster failed")
logging.info("Preparing Cluster.....Done !!!")


(Pdb) c
Traceback (most recent call last):
File "/usr/local/lib/python2.6/logging/__init__.py", line 755, in emit

I think logging.info(out) works the problem is when I add
logging.info(out,err,ret) ,may be there is a better way to supply this
arguments

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.
