Did you try to do
    accountcurrents.finnxlpolicy()
?  You can't do that because the method is not really a part of the
*class*, but rather a part of *instances of the class*.

That's the right way to use the class.

You forgot to include the instance in the parameter list of the
method.  The corrected class is :

class accountcurrents:
#...
   def finnxlpolicy( self ):
       print"world"
