Code Block
d.keySet()

Code Block
d.[iter]values()

Code Block
d.values()

Code Block
[k+1 for k,v in d.iteritems()]

Code Block
d.collect { k, v -> k+1 }

Code Block
d = dict(zip(k, v))

Code Block
k = 1..3 v = 'a'..'c' d = [:]; k.eachWithIndex { it, i -> d[it] = v[i] } println d // [1:"a", 2:"b", 3:"c"]
