AttributeError: module 'sys' has no attribute 'maxint'

In python3, sys.maxint changed to sys.maxsize.

Here are the values:

Python2

>>> sys.maxint9223372036854775807

Python3

>>> sys.maxsize9223372036854775807

On the same platform, the values match. The value is typically 2**31 - 1 on a 32-bit platform and 2**63 - 1 on a 64-bit platform.

Replacing your call to maxint with maxsize will stop this particular Traceback.

python python-3.x sys

You are running your code using python3, which does not have a sys.maxint. Python2, however, does. So run your code as

python2 "D:/PyCharm 2017.2.3/Workplace/maximizer.py"
