用Python在Django中将Unix时间戳转换为人类格式

Question

我想将字符串中的unix时间戳（例如1277722499.82）转换为更人性化的格式（hh:mm:ss或类似格式）。对于django应用程序，在python中有简单的方法可以做到这一点吗？这是一个模板之外，在模型中，我想这样做。谢谢。

编辑 我使用python函数time.time（）生成时间戳。据医生说：

time.time()

Return the time as a floating point number expressed in seconds since the epoch, in UTC. Note that even though the time is always returned as a floating point number, not all systems provide time with a better precision than 1 second. While this function normally returns non-decreasing values, it can return a lower value than a previous call if the system clock has been set back between the two calls.

Answer 1

>>> import datetime
>>> datestring = "1277722499.82"

>>> dt = datetime.datetime.fromtimestamp(float(datestring))
>>> print dt
