[issue17608] configparser not honouring section but not variable case

[Rodney Persky]

New submission from Rodney Persky:

Hey,

Just a fairly small one in the configparser library. I've got a bunch of 
variables with varying capitalisation to indicate words in the variable name.

The config file contains lines such as:
[GlobalSection]
ParameterDelimiterCharacter = ,


Watching the program, at some point (this is straight from a for loop) the 
capitalisation gets lost:
Looking for ['GlobalSection', 'parameterdelimitercharacter']

I'd probably revise this to say it's a quirk - not a bug. As looking over

https://bitbucket.org/ambv/configparser/src/4bf6a6d8ebdf6eec068750a2b940944a9b1b2938/configparser.py?at=default

(the configparser source) information is converted to .lower(). So it seems 
intended for some reason.

Attached is a snippet of code that will reproduce the bug in the context of my 
app.

This is indeed deliberate. If that's unsuitable for you, consider using:

  cp = ConfigParser()
  cp.optionxform = lambda option: option

as described in 
http://docs.python.org/3/library/configparser.html#configparser.optionxform
