I've been trying to find out how to represent a maximum integer, and I've read to use "sys.maxint". However, in Python 3 when I call it I get:

AttributeError: module 'object' has no attribute 'maxing'

In Python 3, sys.maxint does following:-

import sys 

INT_MAX = sys.maxsize 

INT_MIN = -sys.maxsize-1 

print(INT_MAX,INT_MIN)

To know more about this you can have a look at the following video tutorial:-

If you want to determine the maximum size of int in C when compiled the same way as Python was, you can try using the struct module to find out like this:

>>> import struct

>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1

Note: Python 3 ints do not have a maximum.

But, If you are curious about the internal implementation details of Python 3 int objects, then look at sys.int_info for bits per digit and digit size details.
