Huh -- CPython 2.x doesn't let you create an xrange with values past 263-1. CPython 3.x does.

- sltkr 14y agoEven 63-bit integers aren't (all) representable in IEEE double floating point values (that Python uses) which have a 53 bits mantissa. For example, int(float(10¹⁸ - 1)) != 10¹⁸ - 1, but xrange(1, 10¹⁸) is perfectly valid (even in Python 2). edit: how do I type two consecutive asterisks on Hacker News? Backslash doesn't seem to work as an escape character.

- sp332 14y agoIf you put two spaces at the beginning of a line, you'll get a monospaced "literal" mode. For example, int(float(10**18 - 1)) != 10**18 - 1, but xrange(1, 10**18) is perfectly valid (even in Python 2).
