此接口可以获取当前用于存储OP和Tensor描述信息的 ``default main program``。

例如 ``z = paddle.add(x, y)`` 会创建新 ``Op`` 和 tensor ``z`` ，这些变量会被记录在 ``default main program`` 中。

``default main program`` 是许多编程接口中Program参数的默认值。例如对于 ``Executor.run()`` 如果用户没有传入Program参数，会默认使用 ``default main program`` 。

可以使用 :ref:`cn_api_fluid_program_guard` 来切换 ``default main program``。
