python返回当前日期和时间的代码

把开发过程比较好的一些内容片段做个记录，如下内容是关于python返回当前日期和时间的内容，应该是对码农有用处。

import datetime

Get a datetime object

now = datetime.datetime.now()

General functions

print “Year: %d” % now.year
print “Month: %d” % now.month
print “Day: %d” % now.day
print “Weekday: %d” % now.weekday() # Day of week Monday = 0, Sunday = 6
print “Hour: %d” % now.hour
print “Minute: %d” % now.minute
print “Second: %d” % now.second
print “Microsecond: %d” % now.microsecond

ISO Functions

print “ISO Weekday: %d” % now.isoweekday() # Day of week Monday = 1, Sunday = 7
print “ISO Format: %s” % now.isoformat() # ISO format, e.g. 2010-12-24T07:10:52.458593
print “ISO Calendar: %s” % str(now.isocalendar()) # Tuple of (ISO year, ISO week number, ISO weekday)

Formatted date

print now.strftime("%Y/%m/%d") #
