Garbage collection in Python: things you need to know

在 Python 中,每个 variable 都是一个指向一个对象的 reference(pointer),为了追踪 reference 每个 object 中都会有一个 reference count,当对象被 copy 或 delete 则相应的增减或减少其 count,当 count 值为 0 时,则表明已经没有 variable 指向这个 object 了,这时则需要 gc (garbage collector) 将 object 清除,进而回收其占用的内存。当然也可以通过 gc.disable() 禁用 gc ,gc.collect() 手动运行 gc。
