Solve the following python programming problem given the following code:
def _insert_global(self, gv, gty) : 
    '
        Register type *gty* for value *gv*.  Only a weak reference
        to *gv* is kept, if possible.
        ' 
    def on_disposal(wr, pop = self._globals.pop) : 
        pop (wr) 
try : 
        gv = weakref.ref (gv, on_disposal) 
except TypeError : 
        pass 
self._globals [gv] = gv 

    
    

    Fix the buggy line: self._globals [gv] = gv

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

self._globals [gv] = gty
