python中的日期和时间

xhz

datetime 模块提供了以简单和复杂的方式操作日期和时间的类。虽然支持日期和时间算法，但实现的重点是有效的成员提取以进行输出格式化和操作。该模块还支持可感知时区的对象。

>>>
# dates are easily constructed and formatted
from datetime import date
now = date.today()
now
datetime.date(2003, 12, 2)
now.strftime("%m-%d-%y. %d %b %Y is a %A on the %d day of %B.")
'12-02-03. 02 Dec 2003 is a Tuesday on the 02 day of December.'

# dates support calendar arithmetic
birthday = date(1964, 7, 31)
age = now - birthday
age.days
