Python学习——Date and Time

前言：

本文将介绍Python的datetime库：用于跟踪事件发生的时间

我们可以使用datetime库打印日期和时间

注：若想使用此库，需要在程序中加入下述语句，保证可以调用函数库

from datetime import datetime

1、Getting the Current Date and Time

函数：datetime.now()

from datetime import datetime

now = datetime.now()print(now)

2、Extracting Information

函数：.year、.month、.day

from datetime import datetime
now = datetime.now()

current_year = now.year
current_month = now.month
current_day = now.day

3、Hot Date

功能：打印不同规范的日期格式

from datetime import datetime
now = datetime.now()

print '%s-%s-%s' % (now.year, now.month, now.day)
print '%s/%s/%s' % (now.month, now.day, now.year)

4、Pretty Time

功能：打印不同规范的时间格式

from datetime import datetime
now = datetime.now()

print '%s:%s:%s' % (now.hour, now.minute, now.second)

5、Grand Finale

功能：将日期和时间格式混合一起

from datetime import datetime
now = datetime.now()

print '%s/%s/%s %s:%s:%s' % (now.month, now.day, now.year, now.hour, now.minute, now.second)
