How to use long integers in Python to build a range?

Question

I am trying to build a range with an upper bound bigger than limit of integer in Python. I was looking for something like the following:

import sys
start = 100;
step = 100;
limit = sys.maxint + 1;
result = xrange(start, limit, step);

However, xrange parameters are limited to the integer. According to Python Standard Library, I have to use itertools module: islice(count(start, step), (stop-start+step-1)//step), but islice seems to have the same integer limitations for the parameters.

Is there any other way to build the list with upper limit represented by long integer?

Answer 1

xrange is trivial to roll out on your own, so you can do just that:

def xlongrange(start, limit, step):
    n = start
    while n < limit:
        yield n
        n += step
