python 自定義時間 加減天數

---

import datetime



# 現在的時間
setTime ='2015-04-16'
now=datetime.datetime.strptime(setTime,'%Y-%m-%d')
print(now)
# 遞增的時間
delta = datetime.timedelta(days=1)
# 88天后的時間
endnow = now + datetime.timedelta(days=88)#設置小時的就改成hours
# 六天後的時間轉換成字符串
endnow = str(endnow.strftime('%Y-%m-%d'))
offset = now
# 當日期增加到88天后的日期，循環結束
while str(offset.strftime('%Y-%m-%d')) != endnow:
    offset += delta
    print(str(offset.strftime('%Y-%m-%d')))
