ConfigParser reads capital keys and make them lower case

Question

I found one interesting observation. I had written one config file read program as,

import ConfigParser
class  ConfReader(object):
    ConfMap = dict()

    def

ConfigParser.ConfigParser() is a subclass of ConfigParser.RawConfigParser(), which is documented to behave this way:

All option names are passed through the optionxform() method. Its default implementation converts option names to lower case.

That's because this module parses Windows INI files which are expected to be parsed case-insensitively.

You can disable this behaviour by replacing the RawConfigParser.optionxform() function:

self.config = ConfigParser.ConfigParser()
self.config.optionxform = str

str passes through the options unchanged.
