Solve the following python programming problem given the following code:
@ classmethod 
def make_group_dependencies_explicit_for_items(cls, items) : 
    allitems = items 
    items = set ((k for k in allitems if (isinstance (k, Item) or ((type (k) == type) and issubclass (k, Item))))) 
    groups = set ((k for k in allitems if (isinstance (k, Group) or ((type (origitems) == type) and issubclass (k, Group))))) 
    (origitems, origgroups) = (set (items), set (groups)) 
    assert (allitems == items.union (groups)) 
    assert items.isdisjoint (groups) 
    contained_by = defaultdict (set) 
    def iter_group_contents(group) : 
        for k in group.contains : 
            if (k in groups) : 
                for kk in iter_group_contents (k) : 
                    (yield kk) 
else : 
                (yield k) 
for group in groups : 
        for k in iter_group_contents (group) : 
            contained_by [k].add (group) 
for (item, ingroups) in contained_by.items () : 
        assert ingroups.issubset (groups) 
        new_deps = set (item.depends) 
        for g in ingroups : 
            new_deps.update (g.depends) 
item.depends = tuple (new_deps) 
for group in groups : 
        group.contains = set (group.contains) 
        while (not group.contains.isdisjoint (groups)) : 
            for containedgroup in group.contains.intersection (groups) : 
                assert (containedgroup != group) 
                group.contains.update (containedgroup.contains) 
                group.contains.remove (containedgroup) 
for item in items.difference (groups) : 
        assert (item not in groups) 
        if (not groups.isdisjoint (item.depends)) : 
            item.depends = set (item.depends) 
            for groupdep in item.depends.intersection (groups) : 
                item.depends.update (groupdep.contains) 
                item.depends.remove (groupdep) 
item.depends = tuple (item.depends) 
assert groups.isdisjoint (item.depends) 
assert (items == origitems) 
    assert (groups == origgroups) 
    assert (allitems == items.union (groups)) 
    assert items.isdisjoint (groups)...

    
    

    Fix the buggy line: groups = set ((k for k in allitems if (isinstance (k, Group) or ((type (origitems) == type) and issubclass (k, Group)))))

#Here is Python code to fix the buggy line: groups = set ((k for k in allitems if (isinstance (k, Group) or ((type (origitems) == type) and issubclass (k, Group)))))
.

groups = set ((k for k in allitems if (isinstance (k, Group) or ((type (k) == type) and issubclass (k, Group)))))
