将Python字符串拆分成对列表

import re

def split_string_to_pairs(text):
    pattern = r'\b(\w+)\b'  # 匹配单词的正则表达式
    words = re.findall(pattern, text)  # 找到所有匹配的单词
    pairs = [words[i:i+2] for i in range(0, len(words), 2)]  # 将单词按照每两个一对进行拆分
    return pairs

text = "Hello World, how are you doing today?"
pairs = split_string_to_pairs(text)
print(pairs)

[['Hello', 'World'], ['how', 'are'], ['you', 'doing'], ['today']]

def split_string_to_pairs(text):
    words = text.split()  # 将字符串按照空格拆分成单词
    pairs = []
    for i in range(0, len(words), 2):
        pair = [words[i], words[i+1]] if i+1 < len(words) else [words[i]]  # 组成一对或单个单词
        pairs.append(pair)
    return pairs
