Multiple returns from a function
...ue is also used in some functions defined by php itself (e.g. $count in str_replace, $matches in preg_match). This might feel quite different from returning multiple values, but it is worth at least knowing about.
A third method is to use an object to hold the different values you need. This is mor...

...al('2.0'), complex(2,0), Fraction(2,1), '2']:
... print '%15s %s' % (n.__repr__(), isinstance(n, Number))

This is, of course, contrary to duck typing. If you are more ...
Using Kafka as a (CQRS) Eventstore. Good idea?
...el has a direct impact on your scale - don't choose one arbitrarily.

design a stack such that getMinimum( ) should be O(1)
...re's a solution which doesn't do that though, without wrecking the runtime complexity somewhere (e.g. making push/pop O(n)). Note that this doesn't change the complexity of the space required, e.g. if you've got a stack with O(n) space requirements, this will still be O(n) just with a different cons...
