To retrieve a list of nearby entities of an entity, one can use List<Entity> nearby = entity.getNearbyEntities(double x, double y, double z); Bukkit will then calculate a bounding box centered around entity, having as parameters: x: 1/2 the size of the box along x axis y: 1/2 the size ...

Python allows you to hack list comprehensions to evaluate conditional expressions. For instance, [value_false, value_true][<conditional-test>] Example: >> n = 16 >> print [10, 20][n <= 15] 10 Here n<=15 returns False (which equates to 0 in Python). So what Python i...
