条件满足时，如何获取当月和下月的截止日期

import datetime

# 获取当前日期
current_date = datetime.date.today()

# 确定当月的截止日期
last_day_of_current_month = datetime.date(current_date.year, current_date.month, 1) + datetime.timedelta(days=32)
last_day_of_current_month = last_day_of_current_month.replace(day=1) - datetime.timedelta(days=1)

# 确定下月的截止日期
next_month = current_date.replace(day=28) + datetime.timedelta(days=4)
last_day_of_next_month = next_month - datetime.timedelta(days=next_month.day)

# 打印当月和下月的截止日期
print("当月截止日期：", last_day_of_current_month)
print("下月截止日期：", last_day_of_next_month)
