Solve the following python programming problem given the following code:
@ sig ((((H / ((H / 'a') >> 'a')) >> 'a') >> ['a'])) 
def iterate(f, x) : 
    '
    iterate :: (a -> a) -> a -> [a]

    iterate(f, x) returns an infinite List of repeated applications of f to x:
    iterate(f, x) == [x, f(x), f(f(x)), ...]
    ' 
    def __iterate(f, x) : 
        while True : 
            (yield x) 
            x = f (x) 
return L [__iterate (f, f)] 

    
    

    Fix the buggy line: return L [__iterate (f, f)]

#Here is Python program to fix the buggy line: return L [__iterate (f, f)]
.

return L [__iterate (f, x)]
