[ale] Need help with a Python Script

[David Tomaschik]

X = "SomeValue","SomeOtherValue" creates a tuple.  It does NOT do string
concatenation.  + will do concatenation, and is fine to use for one-time
concatenation.  (''.join(list) is better for large quantities.)

Rather than os.getenv('HOSTNAME') consider using socket.gethostname().
It doesn't require that your runtime environment have the HOSTNAME
variable set correctly.  (Which it often is not from cron or other
system-level processes.)

Other than that, see Richard's email.
