Re: [Configobj-develop] syntax

[Oliver S. <oli...@gm...>]

Hi!

the r in front of the string literal designates a raw string (bing that), it tells the python interpreter to handle the characters inside the quotes "as is" and to not interpret the backslash \ as escape. Working alternatives would be to write "c:\\yourpath\\yourfile.ini" or  "c:/yourpath/yourfile.ini" or  """c:\yourpath\yourfile.ini"""

Also for all thing involving paths, better get used to the os.path helper functionalities, i.e.

	import os

	iniLoc = os.path.join(sys.argv[1],'arm.ini')

will give you a well formed path for your environment. Don't concatenate partial paths yourself. 

Also check the documentation for sys.argv, the first element (sys.argv[0]) contains the name of the script you are interpreting.

All the above is easily found in freely available documentation and literature, e.g. http://diveintopython.org/toc/index.html

Your email is kind of off-topic for this mailing list; since you did a smart thing with identifying and using ConfigObj, I'm happy to help you anyway. Have a nice week!

Best regards,

Oliver
