I'm trying to run the following code with Python 3.7:

import sys
print(sys.maxint)

but I get an error:

D:\Python3.7\python.exe "D:/PyCharm 2017.2.3/Workplace/maximizer.py"
Traceback (most recent call last):
File "D:/PyCharm 2017.2.3/Workplace/maximizer.py", line 2, in <module>
    print(sys.maxint)
AttributeError: module 'sys' has no attribute 'maxint'

How do I fix it?

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

Here are the values:

Python2

>>> sys.maxint
9223372036854775807

Python3

>>> sys.maxsize
9223372036854775807

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.
