推荐答案

根据

According to the source code, the maximum size of a list is PY_SSIZE_T_MAX/sizeof(PyObject*).

PY_SSIZE_T_MAX在 pyport.h 为((size_t) -1)>>1

在常规的32位系统上，这是(4294967295/2)/4或536870912.

On a regular 32bit system, this is (4294967295 / 2) / 4 or 536870912.

因此，在32位系统上，python列表的最大大小为 536,870,912 个元素.

Therefore the maximum size of a python list on a 32 bit system is 536,870,912 elements.

只要您拥有的元素数量等于或小于此数量，所有列表函数都应正确运行.

As long as the number of elements you have is equal or below this, all list functions should operate correctly.
