Python 如何将日期字符串转换为不同的格式

How to convert a date string to different format

提问by Chamith Malinda

I need to convert date string"2013-1-25" to string"1/25/13" in python. I looked at the datetime.strptimebut still can't find a way for this.

我需要在python中将日期字符串“2013-1-25”转换为字符串“1/25/13”。我看了看，datetime.strptime但仍然找不到办法。

I assume I have import datetimebefore running each of the lines of code below

我假设我import datetime在运行下面的每一行代码之前

datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')

prints "01/25/13".

打印"01/25/13"。

If you can't live with the leading zero, try this:

如果你不能忍受前导零，试试这个：

dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)

This prints "1/25/13".

这打印"1/25/13".

EDIT: This may not work on every platform:

编辑：这可能不适用于每个平台：

datetime.datetime.strptime("2013-1-25", '%Y-%m-%d').strftime('%m/%d/%y')

If you can live with 01 for January instead of 1, then try...

如果您可以在 1 月份使用 01 而不是 1，那么尝试...

d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

You can check the docsfor other formatting directives.
