Python根据值列表创建所有字典的组合

我想从一定数量的变量范围创建字典，如下所示。

我确实有一个非常基本的工作解决方案，但我想知道是否有一些更简洁的方式来表达相同的想法（我觉得它可以用 itertools 解决？）

a = [1, 2, 3]
b = ["me", "you", "her"]
c = range(1, 5)
d = ["mon", "tues", "wed"]

dic = {"a": None, "b": None, "c": None, "d": None}

for i in a:
    dic["a"] = i
    for j in b:
        dic["b"] = j
        for k in c:
            dic["c"] = k
            for l in d:
                dic["d"] = l
                print(dic)

谢谢

import itertools

a = [1, 2, 3]
b = ["me", "you", "her"]
c = range(1, 5)
d = ["mon", "tues", "wed"]

names = ["a", "b", "c", "d"]
vals = [a, b, c, d]

for comb in itertools.product(*vals):
    dic = dict(zip(names, comb))
    print(dic)
