Solve the following python programming problem given the following code:
def recreate_function(func, module = None, name = None, add_args = [], firstlineno = None) : 
    'Recreate a function, replacing some info.

    :param func: Function object.
    :param module: Module to contribute to.
    :param add_args: Additional arguments to add to function.

    :return: Function copy.
    ' 
    def get_code(func) : 
        return (func.__code__ if six.PY3 else func.func_code)

            func.__code__ = code

            func.func_code = code

        argnames.insert (1, 'co_kwonlyargcount')

set_code (func, CodeType (* args)) 
    if (name is not None) :

return func 

    
    

    Fix the buggy line: args.append (((co_varnames [: code.co_argcount] + tuple (add_args)) + co_varnames [get_code.co_argcount :]))

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

args.append (((co_varnames [: code.co_argcount] + tuple (add_args)) + co_varnames [code.co_argcount :]))
