Convert string to datetime in django?

Question

我想在django模板中以12小时格式显示时间，因为iam将时间数据存储在charecter的eg（'18：30：00'）字段中，如何将此字符串时间数据转换为django / python中的日期？

Answer 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.

Answer 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.

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