如何最好地从Groovy的键列表/值列表中获取地图? [英] How best to get map from key list/value list in groovy?

问题描述

在python中，我可以执行以下操作:

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'}

从键列表和值列表开始，是否有一种很好的方法来构造groovy映射?

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

推荐答案

尝试一下:

def keys = [1, 2, 3]
def values = ['a', 'b', 'c']
def pairs = [keys, values].transpose()

def map = [:]
pairs.each{ k, v -> map[k] = v }
println map

或者:

def map = [:]
pairs.each{ map << (it as MapEntry) }
