python加减日期功能怎么实现

Python中可以使用datetime模块来实现日期的加减功能。具体步骤如下：

from datetime import datetime, timedelta

date = datetime(year, month, day)

# 加一天new_date = date + timedelta(days=1)# 减一天new_date = date - timedelta(days=1)# 加一周new_date = date + timedelta(weeks=1)# 减一周new_date = date - timedelta(weeks=1)

完整示例代码如下：

from datetime import datetime, timedeltadate = datetime(2022, 1, 1)new_date = date + timedelta(days=1)print(new_date)new_date = date - timedelta(days=1)print(new_date)new_date = date + timedelta(weeks=1)print(new_date)new_date = date - timedelta(weeks=1)print(new_date)

这样就可以实现对日期进行加减的功能了。
