是否有更短的方法从字符串中提取日期？

import re

string = "今天是2022-01-01，明天是2022-01-02"
pattern = r"\d{4}-\d{2}-\d{2}"

dates = re.findall(pattern, string)
print(dates)

from datetime import datetime

string = "今天是2022-01-01，明天是2022-01-02"
pattern = "%Y-%m-%d"

dates = [datetime.strptime(date, pattern) for date in string.split() if "-" in date]
print(dates)

from dateutil import parser

string = "今天是2022-01-01，明天是2022-01-02"

dates = [parser.parse(date) for date in string.split() if "-" in date]
print(dates)
