Yes, you are right. Definitely "long" in Python can represent a number much bigger than the native.But the range of returned value from mysql_affected_rows within 0 ~ 2^64-1. No matter how it's converted, the converted value in Python also should in the range of 0 ~ 2^64 - 1.--On Fri, Jul 22, 2016 at 11:50 PM, Eric Snow <ericsnowcurrently@gmail.com> wrote:On Fri, Jul 22, 2016 at 3:02 AM, Stefan Ring <stefanrin@gmail.com> wrote:

Perhaps I misunderstood your meaning, but Python's integers (AKA
"PyLong") can be bigger that a machine-native integer (e.g. 64 bits):
"All integers are implemented as “long” integer objects of *arbitrary
size*." (emphasis mine)
