Hello Andrei,

Thanks. However I am having some problem while using "dircmp" class.

I have the following 2 (identical) directories under my home directory: 
/home/hari/python1 and /home/hari/python2. 

I am getting few error messages, only while using the following attributes: 
diff_files, report(), report_partial_closure(), and report_full_closure().

I am enclosing the error messages for your reference. Am I doing something 
wrong?
