从单词列表创建三元组

Question

假设我有一个单词列表,如下所示:

['The', 'Quick', 'Brown', 'Fox', 'Jumps', 'Over', 'The', 'Lazy', 'Dog']

我想生成一个列表列表,每个数组包含3个单词,但每个单元都有一个可能的三元组.所以看起来应该是这样的:

['The', 'Quick', 'Brown']
['Quick', 'Brown', 'Fox']
['Brown', 'Fox', 'Jumps']

等等.得到这个结果的最佳方法是什么？

Answer 1

>>> words
['The', 'Quick', 'Brown', 'Fox', 'Jumps', 'Over', 'The', 'Lazy', 'Dog']
>>> [words[i:i+3] for i in range(len(words) - 2)]
[['The', 'Quick', 'Brown'], ['Quick', 'Brown', 'Fox'], ['Brown', 'Fox', 'Jumps'], ['Fox', 'Jumps', 'Over'], ['Jumps', 'Over', 'The'], ['Over', 'The', 'Lazy'], ['The', 'Lazy', 'Dog']]

Answer 2

b = [a[i:i+3] for i in range(len(a)-2)]
