Python – 如果他们的名字大写,则加入两个列表对象

是否可以对连续的大写单词进行分组？

例如,我有一个这样的列表：

lst =[['John'],['is'],['smart'],[','],['John'],['Kenneddy'],['is'],['smarter'],[','],['John'],['Fitzgerald'],['Kennedy'],['is'],['best']]

期望的输出：

[['John'],['is'],['smart'],[','],['John','Kenneddy'],['is'],['smarter'],[','],['John','Fitzgerald','Kennedy'],['is'],['best']]

解决方法:

您可以使用groupby通过开头的字母对单词进行分组：

from itertools import groupby

d = [['John'],['is'],['smart'],[','],['John'],['Kenneddy'],['is'],[','],['John'],['Fitzgerald'],['Kennedy'],['is'],['best']]

sum(([[x[0] for x in g]] if k else list(g)
     for k, g in groupby(d, key=lambda x: x[0][0].isupper())),
    [])
