I am using following code.
> GLPK("C:\Documents and > Settings\Amit\Desktop\glpk-4.9\glpk-4.9\examples\"").solve(prob) 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\" -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
