Why does ~True result in -2?
...c in nature - It has two values, True and False, and they are just "customized" versions of the integers 1 and 0 that only print themselves differently. They are subclasses of the integer type int.
So they behave exactly as 1 and 0, except that bool redefines str and repr to display them differentl...

...or here.)
The "find the next prime number" bit is only O(n) overall, amortized — you will move ahead to find the next number only n times in total, not per step. So this whole part of the algorithm takes only O(n).
So using these two you get an upper bound of O(n log log n) + O(n) = O(n log log...
