如何按单词拆分字符串列表并将其转换为子列表？

Question

我想在字符串列表中按单词拆分字符串。我尝试迭代列表，但是我收到一个错误，即 split 不是列表方法。需要的结果是：[["Hi", ",", "how", "are", "you", "?"], ["look", ":", "over", ",", "there"]代码：list1=["Hi, how are you?", "look: over, there"]list2=[]for x in list1:    list2=list1.split()print(list2)

Answer 1

使用正则表达式 --> re.split。

前任：

import re

list1 = ["Hi, how are you?", "look: over, there"]

result = [[j for j in re.split(r"([^A-Za-z])", i) if j.strip()] for i in list1 ]

print(result)

输出：

[['Hi', ',', 'how', 'are', 'you', '?'], ['look', ':', 'over', ',', 'there']]
