pythonでの日付取得・操作について 。 まぁまぁ使いどころがあったので、残しときます。 ```py:Sample.py import datetime from dateutil.relativedelta import relativedelta def Sample(): # 現在時刻 today = datetime.datetime.today() print(today) # >>> 2022-05-16 22:20:06.956045 # 日付指定 happybirthday = datetime.datetime(2000,1,1,0,0,0) print(happybirthday) # >>> 2000-01-01 00:00:00 # 個別に取得 year = happybirthday.year month = happybirthday.month day = happybirthday.day hour = happybirthday.hour minute = happybirthday.minute second = happybirthday.second weekday = happybirthday.weekday() print(f"年：{year}、月：{month}、日：{day}、時：{hour}、分：{minute}、秒：{second}") # >>> 年：2000、月：1、日：1、時：0、分：0、秒：0 # 日付の計算 tomorrow = today + datetime.timedelta(days=1) print(tomorrow) # >>> 2022-05-17 22:20:06.956045 yesterday = today - datetime.timedelta(days=1) print(yesterday) # >>> 2022-05-15 22:20:06.956045 # 年 月の計算 next_year = today + relativedelta(years=1) print(next_year) # 2023-05-16 22:20:06.956045 last_month = today - relativedelta(months=1) print(last_month) # 2022-04-16 22:20:06.956045 if __name__ == "__main__": Sample() ```
