Solve the following python programming problem given the following code:
def _create_render(self) : 
    def process_render_context(next, context, **kwargs) : 
        if (not isinstance (context, Mapping)) : 
            return next () 
desired_args = (self.required + self.defaults.keys ()) 
        for arg in desired_args : 
            if ((not self.overwrite) and (arg in context)) : 
                continue 
context [arg] = kwargs.get (arg, self.defaults.get (arg)) 
return next () 
_req_args = ((['next', 'context'] + self.required) + self.defaults.keys ()) 
    _def_args = dict (self.defaults) 
    process_render_context._argspec = ArgSpec (args = _req_args, varargs = None, keywords = None, defaults = process_render_context) 
    return process_render_context 

    
    

    Fix the buggy line: process_render_context._argspec = ArgSpec (args = _req_args, varargs = None, keywords = None, defaults = process_render_context)

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

process_render_context._argspec = ArgSpec (args = _req_args, varargs = None, keywords = None, defaults = _def_args)
