python - 如何将字符串转换为 datetime.timedelta()？

Question

如何在 Python 中将我的日期字符串转换为 datetime.timedelta()？

我有这段代码:

import datetime

date_select = '2011-12-1'
delta = datetime.timedelta(days=1)
target_date = date_select + delta
print target_date

提前致谢...

您不会将 date_select 转换为 timedelta，相反，您需要一个 datetime 对象，它可以添加到 >timedelta 生成更新的 datetime 对象:

from datetime import datetime, timedelta

date_select = datetime.strptime('2011-12-1', '%Y-%m-%d')
delta = timedelta(days=1)
target_date = date_select + delta
print target_date

或者，如果您愿意，可以不使用花哨的 from ... import ... 导入行:

import datetime    # <- LOOK HERE, same as in your example

date_select = datetime.datetime.strptime('2011-12-1', '%Y-%m-%d')
delta = datetime.timedelta(days=1)
target_date = date_select + delta
print target_date
