回答1:

If you absolutely must do this, use time.strptime. It would be a better idea not to store structured data in a string if you can avoid it, though.

回答2:

Within Django's templates you can use the date Template Filter:

{{ value|date:"h:i:s a" }}   # '18:30:00' would appear as  6:30:00 p.m. {{ value|date:"g:i:s a" }}   # '18:30:00' would appear as 06:30:00 p.m. 

value would be the string variable you pass in the Context to the Template when you render it. The string appearing after date: formats the time.

You can find more here: http://docs.djangoproject.com/en/1.3/ref/templates/builtins/#date

Hank Gay's answer is more correct than mine; you should avoid keeping structured data in a string if at all possible.
