Solve the following python programming problem given the following code:
@ contextlib.contextmanager 
def forbid_codegen() : 
    "
    Forbid LLVM code generation during the execution of the context
    manager's enclosed block.

    If code generation is invoked, a RuntimeError is raised.
    " 
    from numba.targets import codegen 
    patchpoints = ['CodeLibrary._finalize_final_module'] 
    old = { 
        
} 
    def fail(* args, **kwargs) : 
        raise RuntimeError ('codegen forbidden by test case') 
try : 
        for name in patchpoints : 
            parts = name.split ('.') 
            obj = codegen 
            for attrname in parts [: (- 1)] : 
                obj = getattr (obj, attrname) 
attrname = parts [(- 1)] 
            value = getattr (old, attrname) 
            assert callable (value), ('%r should be callable' % name) 
            old [(obj, attrname)] = value 
            setattr (obj, attrname, fail) 
(yield) 
finally : 
        for ((obj, attrname), value) in old.items () : 
            setattr (obj, attrname, value) 

    
    

    Fix the buggy line: value = getattr (old, attrname)
assistant
#Here is Python program to fix the buggy line: value = getattr (old, attrname)
.

value = getattr (obj, attrname)
