我似乎不明白我应该如何使用Python的datetime.timedelta函数来计算明天的日期。
示例:
from datetime import datetime, timedelta
print(datetime.now())
print( datetime.now() + timedelta(hours=24))
输出:
2015-02-22 14:51:11.515000
2015-02-23 05:18:30.728056
但第二行应该更像:
2015-02-23 14:51:11
您可以在行动here中看到这一点。
更新感谢大家的意见!显然,timedelta
在Python 2.7.2 [1]上被打破了 - 很高兴找到修复的版本。

timedelta的实施已经破裂:
timedelta(hours=24)
=> datetime.timedelta(0, 52039, 213056)
应该是1天(或86400秒,这是52039秒和213056微秒)
此外,中间值失败:
timedelta(seconds=65000)
Internal error: Assertion failed: 0 <= temp && temp < 1000000

您链接的python似乎已被破坏,结果在我的机器上:
>>> from datetime import datetime, timedelta
>>> print(datetime.now())
2015-02-22 15:03:44.447179
>>> for i in range(24):
... print( datetime.now() + timedelta(hours=i))
...
