Solve the following python programming problem given the following code:
def __init__(self, target, onDelete = None) : 
    'Return a weak-reference-like instance for a bound method

        target -- the instance-method target for the weak
            reference, must have __self__ and __func__ attributes
            and be reconstructable via:
                target.__func__.__get__(target.__self__)
            which is true of built-in instance methods.
        onDelete -- optional callback which will be called
            when this weak reference ceases to be valid
            (i.e. either the object or the function is garbage
            collected).  Should take a single argument,
            which will be passed a pointer to this object.
        ' 
    def remove(weak, self = self) : 
        'Set self.isDead to true when method or instance is destroyed' 
        methods = self.deletionMethods [:] 
        del self.deletionMethods [:] 
        try : 
            del self.__class__._allInstances [self.key] 
except KeyError : 
            pass 
for function in methods : 
            try : 
                if callable (function) : 
                    function (self) 
except Exception as e : 
                try : 
                    traceback.print_exc () 
except AttributeError : 
                    print (('Exception during saferef %s cleanup function %s: %s' % (self, function, e))) 
self.deletionMethods = [remove] 
    self.key = self.calculateKey (target) 
    self.weakSelf = weakref.ref (target.__self__, remove) 
    self.weakFunc = weakref.ref (target.__func__, remove) 
    self.selfName = str (target.__self__) 
    self.funcName = str (target.__func__.__name__) 

    
    

    Fix the buggy line: self.deletionMethods = [remove]

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