Python integers are effectively big integers, no need of a special class. Just use normal integers. If in doubt try this (using Python v2): >>> print 2 ** 500 327339060789614187001318969682759915221664204604306 478948329136809613379640467455488327009232590415715 0886684127560071009217256545885393053328527589376L Notice the L at the end? That tells you python is using a long integer. You only see that in Python v2. If you are using v3 there is no L and no distinction between long and regular integers. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
