Python获取时间

1. 获取当前时间
   代码：

import datetime

now = datetime.datetime.now()

print "current date and time %s" % str(now)

print "current year: %d" % now.year
print "current month: %d" % now.month
print "current day: %d" % now.day
print "current hour: %d" % now.hour
print "current minute: %d" % now.minute
print "current second: %d" % now.second
print "current microsecond: %d" % now.microsecond
print "current date and time %s" % now.strftime("%Y-%m-%d %H:%M")

输出：

current month: 1
current day: 18
current hour: 14
