Others have addressed your specific question. I'm going to make
a different suggestion. Change your thinking so that you can use
ConfigParser to get your values from a .INI/.CONF file instead.
The file would look something like:
[section001]
m=queuemanager
server=myserver
port=1080
key=somekey
object=someobject
c=20
[EMAIL PROTECTED]
[section002]
.
. If you have many of these just put things in a loop
. and process each section
.
You can then read with (not tested):
import ConfigParser
inifilename='program.ini'
INI=ConfigParser.ConfigParser()
INI.read(inifilename)
section='section001'
option='m'
try: m=INI.get(section, option)
except: m=None
option='server'
try: server=INI.get(section, option)
except: server=None
option='port'
try: port=INI.getint(section, option)
except: port=None # Or set to default port
option='key'
try: key=INI.get(section, option)
except: key=None
option='object'
try: object=INI.get(section, option)
except: object=None
option='c'
try: c=INI.getint(section, option)
except: c=None
option='emailtolist'
try: emailtolist=INI.get(section, option).split(';')
except: emailtolist=None
Just a suggestion.
