.. method:: RawConfigParser.optionxform(option)

Transforms the option name *option* as found in an input file or as passed in by
321
client code to the form that should be used in the internal structures. The
322
default implementation returns a lower-case version of *option*; subclasses may
323
override this or client code can set an attribute of this name on instances to
324
affect this behavior. Setting this to :func:`str`, for example, would make
325
option names case sensitive.

You don't necessarily need to subclass a ConfigParser to use this method, you
327
can also re-set it on an instance, to a function that takes a string
328
argument. Setting it to ``str``, for example, would make option names case
331
cfgparser = ConfigParser()
333
cfgparser.optionxform = str
335
Note that when reading configuration files, whitespace around the
336
option names are stripped before :meth:`optionxform` is called.
