Normally, I code as follows for getting a particular item in a variable as follows
config = ConfigParser.ConfigParser()
except ConfigParser.MissingSectionHeaderError, e:
self.makeDB = config.get("DB","makeDB")
self.makeDB = 0
val["A"]["x"] = 1
val["B"]["z"] = 3
I suggest subclassing
SafeConfigParser, &c) to safely access the "protected" attributes (names starting with single underscore -- "private" would be names starting with two underscores, not to be accessed even in subclasses...):
import ConfigParser class MyParser(ConfigParser.ConfigParser): def as_dict(self): d = dict(self._sections) for k in d: d[k] = dict(self._defaults, **d[k]) d[k].pop('__name__', None) return d
This emulates the usual logic of config parsers, and is guaranteed to work in all versions of Python where there's a
ConfigParser.py module (up to 2.7, which is the last of the
2.* series -- knowing that there will be no future Python 2.any versions is how compatibility can be guaranteed;-).
If you need to support future Python
3.* versions (up to 3.1 and probably the soon forthcoming 3.2 it should be fine, just renaming the module to all-lowercase
configparser instead of course) it may need some attention/tweaks a few years down the road, but I wouldn't expect anything major.
