如何从字符串列表中获取时间值？

import re
from datetime import datetime

def get_time_values(string_list):
    time_values = []
    time_format = r"\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}"  # 时间格式正则表达式

    for string in string_list:
        match = re.match(time_format, string)
        if match:
            time_str = match.group()
            time_obj = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")
            time_values.append(time_obj)
        else:
            # 处理不符合时间格式的字符串
            pass

    return time_values
