如何查找每行两个日期之间的行

import re

def find_rows_between_dates(file_path, start_date, end_date):
    pattern = r'\b\d{4}-\d{2}-\d{2}\b'  # 匹配日期格式为YYYY-MM-DD的正则表达式
    result = []

    with open(file_path, 'r') as file:
        for line in file:
            dates = re.findall(pattern, line)
            if len(dates) >= 2:
                date1 = dates[0]
                date2 = dates[1]
                if start_date <= date1 <= end_date or start_date <= date2 <= end_date:
                    result.append(line)

    return result

# 使用示例
file_path = 'example.txt'  # 替换为你的文件路径
start_date = '2022-01-01'  # 替换为开始日期
end_date = '2022-12-31'  # 替换为结束日期

rows_between_dates = find_rows_between_dates(file_path, start_date, end_date)
for row in rows_between_dates:
    print(row)
