Solve the following python programming problem given the following code:
def mutator(mutate) : 
    'Return an inspyred mutator function based on the given function.
    
    This function generator takes a function that operates on only
    one candidate to produce a single mutated candidate. The generator 
    handles the iteration over each candidate in the set to be mutated.

    The given function ``mutate`` must have the following signature::
    
        mutant = mutate(random, candidate, args)
        
    This function is most commonly used as a function decorator with
    the following usage::
    
        @mutator
        def mutate(random, candidate, args):
            # Implementation of mutation
            pass
            
    The generated function also contains an attribute named
    ``single_mutation`` which holds the original mutation function.
    In this way, the original single-candidate function can be
    retrieved if necessary.
    
    ' 
    @ functools.wraps (mutate) 
    def inspyred_mutator(random, candidates, args) : 
        mutants = [] 
        for (i, cs) in enumerate (candidates) : 
            mutants.append (mutate (random, cs, args)) 
return mutants 
inspyred_mutator.single_mutation = inspyred_mutator 
    return inspyred_mutator 

    
    

    Fix the buggy line: inspyred_mutator.single_mutation = inspyred_mutator

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

inspyred_mutator.single_mutation = mutate
