如何从起始两个单词相同的单词列表中获取单词列表

这是使用的一种方法collections.defaultdict。

例如：

from collections import defaultdict

lst = ["customer service skill","sales representative","customer service","customer service experience"]
result = defaultdict(list)
for i in lst:
    result[tuple(i.split()[:2])].append(i)   #Key = starting two words
print(list(result.values()))

或使用 dict.setdefault

例如：

lst = ["customer service skill","sales representative","customer service","customer service experience"]
result = {}
for i in lst:
    result.setdefault(tuple(i.split()[:2]), []).append(i)   #Key = starting two words
print(list(result.values()))

输出：

[['customer service skill', 'customer service', 'customer service experience'], ['sales representative']]
