Eric V. Smith added the comment:
2to3 is not designed to turn every valid python2 program into a valid python3
program. You'll have to provide a way to compare GameClock objects. I suggest
you look at http://python3porting.com. You should read the whole site, it's a
great resource.
New submission from Xinmeng Xia :
After conversion of 2to3 , run simple-example.py and the following error will
happen.
Traceback (most recent call last):
