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

    
    

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

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