Note: This won't work...
Difference between const & const volatile
... marked as being volatile, a couple problems might occur:
the while loop test might read the status register only once, since the compiler could assume that whatever it pointed to would never change (there's nothing in the while loop test or loop itself that could change it). If you entered the f...

How can I represent an 'Enum' in Python?

@shahjapan: Interesting, but relatively slow: a test is done for each access like Animals.DOG; also, the values of the constats are strings, so that comparisons with these constants are slower than if, say, integers were allowed as values.

Your sympy.Rational test doesn't quite do what you're thinking, because sympy.Rational(5) evaluates to an instance of sympy.Integer. Any operation that would produce a Rational with an integer value instead produces an Integer.

Which is fastest? SELECT SQL_CALC_FOUND_ROWS FROM `table`, or SELECT COUNT(*)
...
IMHO, the reason why 2 queries
SELECT * FROM count_test WHERE b = 666 ORDER BY c LIMIT 5;
SELECT count(*) FROM count_test WHERE b = 666;

SELECT SQL_CALC_FOUND_ROWS * FROM count_test WHERE b = 555 ORDER BY c LIMIT 5;
has to be see...
