I would "reverse" that check and test `obj` for not being a string::

 for obj in Array:
     if not isinstance(obj, basestring):
         for item in obj:
             print item
     else:
         print obj

This way it works with other types of iterables than lists too.  Often
strings are the only type that one don't want to iterate over in such a
context.
