The last character in that string is a double quote. You don't want that. What 
you want to do is escape all of the backslashes (or use raw strings to avoid the 
escaping altogether). E.g.

   "C:\\Documents and Settings\\Amit\\Desktop\\glpk-4.9\\glpk-4.9\\examples\\"

or

   r"C:\Documents and Settings\Amit\Desktop\glpk-4.9\gplk-4.9\examples\"
