将包含pm的小时字符串转换为日期时间

import datetime

def convert_string_to_datetime(time_str):
    # 提取小时数和分钟数
    hour = int(time_str[:2])
    minute = int(time_str[3:5])

    # 判断上午或下午
    if hour < 12:
        hour += 12

    # 构建日期时间对象
    now = datetime.datetime.now()
    date_time = datetime.datetime(now.year, now.month, now.day, hour, minute)

    return date_time

# 示例输入字符串
time_str = "08:30pm"

# 转换为日期时间对象
result = convert_string_to_datetime(time_str)

# 输出结果
print(result)
