Python 支持bignum"整数类型，它可以处理任意大的数字.在 Python 2.5+ 中，这种类型被称为 long 并且与 int 类型分开，但解释器会自动使用更合适的那个.在 Python 3.0+ 中，int 类型已完全删除.

Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.

不过，这只是一个实现细节——只要您有 2.5 或更高版本，只需执行标准数学运算，任何超出 32 位数学边界的数字都会自动(并且透明地)转换为 bignum.

That's just an implementation detail, though — as long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.

您可以在 PEP 0237 中找到所有血腥细节.
