Solve the following python programming problem given the following code:
@ unittest.expectedFailure 
def test_return_annotations_alone(self) : 
    before = "def foo() -> 'bar': pass" 
    after = "
        def foo(): pass
        foo.__annotations__ = {'return': 'bar'}
        " 
    self.convert_check (before, after, from3 = True) 
    b = '
        def foo() -> "bar":
            print "baz"
            print "what\'s next, again?"
        ' 
    a = '
        def foo():
            print "baz"
            print "what\'s next, again?"
        ' 
    self.convert_check (before, a, from3 = True) 

    
    

    Fix the buggy line: self.convert_check (before, a, from3 = True)
assistant
#Here is Python program to fix the buggy line: self.

self.convert_check (b, a, from3 = True)
