Solve the following python programming problem given the following code:
def test_map_dict(self) : 
    def mapTest(val, key, * args) : 
        return val.upper () 
map = _ ({ 
        'foo' : 'bar', 
        'bar' : 'foo', 
}).map (mapTest) 
    self.assertEqual ({ 'BAR', 'FOO' }, set (map), 'map for dicts did not work') 
    map = _ ({ 
        'foo' : 'bar', 
        'bar' : 'foo', 
}).collect (mapTest) 
    self.assertEqual ({ 'BAR', 'FOO' }, set (mapTest), 'collect for dicts did not work') 

    
    

    Fix the buggy line: self.assertEqual ({ 'BAR', 'FOO' }, set (mapTest), 'collect for dicts did not work')

#Here is Python program to fix the buggy line: self.

self.assertEqual ({ 'BAR', 'FOO' }, set (map), 'collect for dicts did not work')
