With a normal dictionary, I can specify a default fallback value
in the event the requested key isn't present:
d = {}
print d.get(42, 'Some default goes here')
However, with the ConfigParser object, there doesn't seem to be
any way to do a similar
cp = ConfigParser(...)
# ...
print cp.get('MySection', 'MyValue', 'Some default goes here')
that, in the event either "MySection" doesn't exist in the config
file, or "MyValue" doesn't exist within "MySection", it simply &
quietly returns my default. At the moment, I have to mimic this with
try:
val = cp.get('MySection', 'MyValue')
except (NoSectionError, NoOptionError), e:
val = 'Some default goes here'
print val
which is a real pain when you have multiple options, some using
various combinations of get(), getboolean(), getint(), or
getfloat(). Yes, I can write some cheap wrappers to do these,
but it feels like something that should be built-in.
I've played with the DEFAULT, but that seems to just create its
own section that I have to *ask* for:
cp.get('DEFAULT', 'MyValue')
I've thumbed through the source to ConfigParser.py but don't see
any indication that it's possible to do what I'd like short of
wrapping all my cp.get*() calls in try/except blocks or creating
a forked version of ConfigParser.py locally. Is there anything
I'm missing, or a better workaround to this?
Thanks,
