如何在Python中将日期时间字符串中的时间从24:00转换为00:00？

from datetime import datetime

date_str = "2023-05-20 24:00:00"

# 替换"24:00"为"00:00"并增加1天
if "24:00" in date_str:
    dt = datetime.strptime(date_str.replace("24:00", "00:00"), "%Y-%m-%d %H:%M:%S")
    dt = dt.replace(day=dt.day + 1)  # 增加1天
else:
    dt = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S")

print(dt)  # 输出: 2023-05-21 00:00:00

from dateutil.parser import parse

date_str = "2023-05-20 24:00:00"
dt = parse(date_str)
print(dt)  # 输出: 2023-05-21 00:00:00

import re
from datetime import datetime, timedelta

date_str = "2023-05-20 24:00:00"

# 正则匹配并替换
if re.search(r'24:00:\d{2}', date_str):
    dt = datetime.strptime(re.sub(r'24:00', '00:00', date_str), "%Y-%m-%d %H:%M:%S")
    dt += timedelta(days=1)  # 增加1天
else:
    dt = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S")

print(dt)
