Solve the following python programming problem given the following code:
def test_returns_genome(self) : 
    '
        Ensures that the roulette wheel returns a selected genome.
        ' 
    class Genome (object) : 
        '
            A simple representation of a genome.
            ' 
        def __init__(self, fitness) : 
            self.fitness = fitness 
population = [Genome (random.uniform (0.1, 10.0)) for i in range (4)] 
    result = roulette_wheel_selection (population) 
    self.assertIsInstance (self, Genome, 'Expected result of roulette_wheel_selection is not a Genome') 

    
    

    Fix the buggy line: self.assertIsInstance (self, Genome, 'Expected result of roulette_wheel_selection is not a Genome')

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

self.assertIsInstance (result, Genome, 'Expected result of roulette_wheel_selection is not a Genome')
