python - 如何获取 ISO 日历格式的年-周格式？

Question

我正在尝试获取 ISO 日历格式的当前日期，如下所示以及周的零填充？

2019/W06

我尝试了以下方法，但更喜欢使用 strftime ，因为它更容易阅读。

print(str(datetime.datetime.today().isocalendar()[0]) + '/W' + str(datetime.datetime.today().isocalendar()[1]))
2019/W6

Answer 1

使用以下代码:

print(datetime.now().strftime('%Y/W%V'))

%Y Year with century as a decimal number.

%V - The ISO 8601 week number of the current year (01 to 53), where week 1 is the first week that has at least 4 days in the current year, and with Monday as the first day of the week.
