How best to get map from key list/value list in groovy?

Question

In python, I can do the following:

keys = [1, 2, 3]
values = ['a', 'b', 'c']
d = dict(zip(keys, values))

assert d == {1: 'a', 2: 'b', 3: 'c'}

Is there a nice way to construct a map in groovy, starting from a list of keys and a list of values?

Answer 1

There's also the collectEntries function in Groovy 1.8

def keys = [1, 2, 3]
def values = ['a', 'b', 'c']
[keys,values].transpose().collectEntries { it }
