Solve the following python programming problem given the following code:
def pytest_funcarg__sprinkler_bbn(request) : 
    'Sprinkler BBN built with build_bbn.' 
    def f_rain(rain) : 
        if (rain is True) : 
            return 0.2 
return 0.8 
def f_sprinkler(rain, sprinkler) : 
        if ((rain is False) and (sprinkler is True)) : 
            return 0.4 
if ((rain is False) and (sprinkler is False)) : 
            return 0.6 
if ((rain is True) and (sprinkler is True)) : 
            return 0.01 
if ((rain is True) and (sprinkler is False)) : 
            return 0.99 
def f_grass_wet(sprinkler, rain, grass_wet) : 
        table = dict () 
        table ['fft'] = 0.0 
        table ['fff'] = 1.0 
        table ['ftt'] = 0.8 
        table ['ftf'] = 0.2 
        table ['tft'] = 0.9 
        table ['tff'] = 0.1 
        table ['ttt'] = 0.99 
        table ['ttf'] = 0.01 
        return table [make_key (sprinkler, rain, grass_wet)] 
return build_bbn (f_rain, f_grass_wet, f_grass_wet) 

    
    

    Fix the buggy line: return build_bbn (f_rain, f_grass_wet, f_grass_wet)
