Solve the following python programming problem given the following code:
def partition(self, predicate = None) : 
    '
        Split an array into two arrays: one whose elements all satisfy the given
        predicate, and one whose elements all do not satisfy the predicate.
        ' 
    predicate = self._lookupIterator (predicate) 
    pass_list = [] 
    fail_list = [] 
    def by(elem, index, * args) : 
        (pass_list if predicate (elem) else fail_list).append (elem) 
_.each (self.obj, by) 
    return self._wrap ([pass_list, predicate]) 

    
    

    Fix the buggy line: return self._wrap ([pass_list, predicate])
assistant
#Here is Python code to fix the buggy line: return self.

return self._wrap ([pass_list, fail_list])
