How did Python find 5 in a dictionary containing 5.0? Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is requir...

While the ball does indeed bounce an infinite number of times, with the bounces getting smaller and smaller in height, that doesn’t mean it keeps bouncing forever. The bounces get smaller and smaller not only in height, but also in duration, and the sum of their durations converges to a...

Sadly, bribes are quite common in many parts of the world, although often – as in Kathmandu – they tend to be aimed at locals rather than tourists. However, that doesn’t mean that visitors cannot be subjected to this special treatment, and when they are it does present a bit of a ...
