python-->date、datetime、string相互轉換

Python--常用時間類型格式之間的轉換

import datetime
import time

# 1.string轉datetime

>>> str = '2012-11-19'
>>> date_time = datetime.datetime.strptime(str,'%Y-%m-%d')
>>> date_time

result: datetime.datetime(2012,11,19,0,0)

# 2.datetime轉string

>>>date_time.strftime('%Y-%m-%d')

result: '2012-11-19'

# 3.datetime轉時間戳

>>> time_time = time.mktime(date_time.timetuple())
>>> time_time

result: 1353254400.0

# 4.時間戳轉string

>>>time.strftime('%Y-%m-%d',time.localtime(time_time))

result: '2012-11-19'

# 5.date轉datetime

>>> date = datetime.date.today()
>>> date

result: datetime.date(2012,11,19)

# 6.將date轉換為str，在由str轉換為datetime
>>> datetime.datetime.strptime(str(date),'%Y-%m-%d')   

result: datetime.datetime(2012,11,19,0,0)
