Solve the following python programming problem given the following code:
@ util.inlineCallbacks 
def statustest_inlinecallbacks_util(self) : 
    def raiser(_ = None) : 
        raise Exception ('raised exception') 
foo = (yield util.maybeDeferred (foo)) 

    
    

    Fix the buggy line: foo = (yield util.maybeDeferred (foo))
assistant
#Here is Python program to fix the buggy line: foo = (yield util.

foo = (yield util.maybeDeferred (def raiser())
