一、datetime模块
1)date 日期对象,常用的属性有year,month,day
2)time 时间对象,常用的属性有:hour,minute,second,microsecond
3)datetime 日期时间对象,常用的属性有year,month,day,hour,minute,second,microsecond
4)timedelta 时间间隔,即两个时间点之间的长度
5)tzinfo 时区信息对象
演示:
import datetime
# 1 日期(年份,月份和日期)
date01 = datetime.date.today()
print(date01)
print("年份", date01.year)
print("月份", date01.month)
print("日期", date01.day)
# 2 时间(时,分,秒,微秒,时区)
time01 = datetime.time(12, 12, 12, 121212)
print(time01)
print("时:", time01.hour)
print("分:", time01.minute)
print("秒:", time01.second)
print("微妙:", time01.microsecond)
# 3 datetime 时间日期(年份、月份、日期、时、分、秒、微妙、时区)
datetime01 = datetime.datetime.now()
print(datetime01)
print("年份", datetime01.year)
print("月份", datetime01.month)
print("日期", datetime01.day)
print("时:", datetime01.hour)
print("分:", datetime01.minute)
print("秒:", datetime01.second)
print("微妙:", datetime01.microsecond)
# 4 三种类型的转换
print("datetime中取date:", datetime01.date())
print("datetime中取time:", datetime01.time())
print("date和time组合成datetime:", datetime.datetime.combine(date01,time01))
# 5 timeDelta 时间间隔
date01 = datetime.date(2012, 12, 12)
date02 = datetime.date(2008, 5, 27)
print((date01 - date02).days)
