Itertools等效于嵌套循环“对于xs中的x:对于ys中的y ...". [英] Itertools equivalent of nested loop "for x in xs: for y in ys..."

问题描述

我有一个嵌套循环，可以在一组共轭动词中创建所有组合.目的是获取动词，人称和时态的所有可能组合，例如[['to be', 'first person singular', 'future'],['to be', 'second person singular', 'future'], ...].

I have a nested loop to create all combinations in a set of conjugated verbs. The aim to to get all possible combinations of verb, person and tense, e.g. [['to be', 'first person singular', 'future'],['to be', 'second person singular', 'future'], ...].

for v in verbs:
    for p in persons:
        for t in tenses:
            return [v, p, t]

是否有可能使用itertools减少嵌套的方法?

Is there a way of reducing the nesting, perhaps using itertools?

推荐答案

for v, p, t in itertools.product(verbs, persons, tenses):
    ...
