Python正则表达式按人名分组句子

import re

def group_sentences_by_name(sentence):
    # 定义正则表达式模式匹配人名
    pattern = r'([A-Z][a-z]+)'

    # 使用正则表达式模式匹配句子中的人名
    matches = re.findall(pattern, sentence)

    # 将人名按照不同的组进行分组
    name_groups = {}
    for name in matches:
        if name in name_groups:
            name_groups[name].append(sentence)
        else:
            name_groups[name] = [sentence]

    return name_groups

# 测试代码
sentence = "John said hi to Lisa. Lisa replied hello to John."
name_groups = group_sentences_by_name(sentence)
for name, sentences in name_groups.items():
    print(f"Name: {name}")
    print(f"Sentences: {sentences}\n")
