请允许我说,我有<条码>级A(<}......>>:通过。 我是否应当明确打上“<条码>,请删除”。 让我更具体地说: 不久前,与现在的read合发生了什么? 当一个胎面与另一个胎盘交织时,它是否rash或使用点子?

www.un.org/chinese/sc/presidency.asp 关键词实际上并未明确删除物体。 它删除了参考数字,如果没有其他用途,则垃圾收集器清理了记忆。 如果你有一套将持续很长时间的法典,以及一个能够给你再不需要的记忆留下大量记忆的变量,那将是有益的。
一旦你离开职能范围,所有变量的参考量将予以减少(并酌情清理)。 没有任何><>>>。
我也要提到,<代码>del的指令从地方范围删除了变称。 因此,从您的角度来看,变量已经消失。 然而,如果提及所指明的物体,则不会清理记忆本身。

Forks don t merge. You can wait on a fork to exit, but that s it. And when you join another thread, they aren t being merged there either. They have different stacks (but the same heap). When a thread ends, all variables within that thread s scope have their reference count decremented (and cleaned up if appropriate). I don t understand you question about thrashing and pointers -- I have no idea what thrashing means, and python doesn t have pointers.
