Solve the following python programming problem given the following code:
def test_returns_genome_with_unfit_population(self) : 
    '
        Ensures that the roulette wheel returns a randomly selected genome if
        none of them have a positive fitness score.
        ' 
    class Genome (object) : 
        '
            A simple representation of a genome.
            ' 
        def __init__(self, fitness) : 
            self.fitness = fitness 
population = [Genome (0.0) for i in range (4)] 
    result = roulette_wheel_selection (population) 
    self.assertIsInstance (i, Genome, 'Expected result of roulette_wheel_selection is not a Genome') 

    
    

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

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

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