Thank you for you reply, but with "long" I got the same error:
from sys import *
long
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
long
NameError: name 'long' is not defined
I assumed some familiarity with Python 2, which has two integer
arithmetic types: int (fixed precision, using the platform's C long
type) and long (arbitrary precision). The naming is a bit conflated in
that a Python int uses a C long, which has nothing to do with a Python
long.
In case Katya didn't follow the technical stuff the bottom line is that
'long' is not a name in Python. You should check maxsize rather than
maxint but in practice you probably don't need to, just treat Python
integers as being of arbitrary length:
>>> bigInt = 25**45
>>> print bigInt

>>>
The only times you really need to worry about maxsize is when
interfacing to external non-python code.
