QOTW: "Software doesn't work, and hardware is unreliable. If you wait for a
guarantee that nothing will go wrong, you'll end up being my age in a just a
few dozen short decades, but without the rollicking good memories that make
me such an agreeable old fart <wink>." - Tim Peters
"The first rule about __slots__ is: don't use them! OTOH the second rule (for
expert only) is: don't use them!" - Michele Simionato
When you are switching from, say, Java you will probably be surprised that
in Python p = 2**24036583 - 1 is all it takes to calculate the largest
known prime number to date. Printing p will also work out of the box, but
may take a bit long. Tim Peters sketches the algorithm Python uses to
generate the decimal representation of an integer and provides code
that can handle very large numbers efficiently.
