Question

In python I need to be able to cycle through a 19 digit number; what is the typical way of doing this? I’m using python 2.7.x; but will use python 3.x if there is a viable solution.

I have a large number; 1000**5 (and even larger 1000**10) for example; I need to cycle through this number list in a for loop. I am aware of the time it will take; but because I cannot find a way to cycle through such a big number I’m at a loss.

I’ve tried with xrange, range, and itertools.islice in python 2.7 and receive Overflow errors.

Thanks

The following is true for python 3.x:

The int type in python does not have a limit. If you want to iterate through 0,1,2…n where n is a 19-digit number, you can just do:

for i in range(n):
    pass #whatever you like

Although that would take a very long time.
