Long Long Int in python

Question

I have a task to calculate a sum of very big integers. the sum could be over the limit of max value of int. I'd like to use long long int type like in c to prevent this. python is dynamic type language. but there must be someway to declare this long long int type. help me to declare long long int type in python. thanks

It will take the value as long as you have enough memory :) — han solo

no matter how big they are, I think python will handle it. love python : ) — recnac

You don't declare types in Python. That's why it is called a dynamic language. — quamrana

Python 3 int has no maximum value. Even in Python 2, where int had some (platform-specific) maximum, results were promoted to the unbounded long type as necessary. There was virtually no semantic difference between int and long; the distinction represented an implementation detail that was swept under the rug in Python 3. — chepner

You don't need to.

>>> sum([
...     1243926478235632786572938657832682396538279658237956832976482375678239659782365,
...     23590237589734985720423803758031640192748372946743079324780137092704730297409327409237409237432,
... ])

Python has arbitrary-size integers, that can become way larger than C's long long.
