python转换字符串为datetime类型详解编程语言

python中通过日期转换函数把字符串格式的日期转换成datetime格式的日期格式

time.strptime() converts the string to a struct_time tuple.

time.mktime() converts this tuple into seconds (elasped since epoch, C-style).

datetime.fromtimestamp() converts the seconds to a Python datetime object.

>>> import datetime,time 
>>> stringDate = "2006-05-18 19:35:00" 
>>> dt = datetime.datetime.fromtimestamp(time.mktime(time.strptime(stringDate,"%Y-%m-%d %H:%M:%S"))) 
>>> print dt 
2006-05-18 19:35:00 
>>> print type(dt) 
<type 'datetime.datetime'> 
>>>
