python 格式化日期
python格式化日期的方法：可以利用time.asctime(time.local(time.time()))函数来格式化日期。如果我们要获取当前日期，可以利用时间函数time()来获取。
python 格式化日期到毫秒
可以参考下面的代码：
一、代码一：
importdatetime
print(datetime.datetime.now().microsecond*1e-3)
二、代码二：
importdatetime
now=datetime.datetime.now()
printnow.strftime("%Y%m%d%H%M%S")
扩展资料：
python函数
hasattr(obj,name)查看一个obj的namespace中是否有name
getattr(obj,name)得到一个obj的namespace中的一个name
setattr(obj,name,value)为一个obj的namespace中的一个name指向vale这个object
delattr(obj,name)从obj的namespace中删除一个name

python，格式化时间实例，求
对于像'Wed, 11 Apr 2012 09:37:05 +0800'的时间格式化可如下解：
date='Wed, 11 Apr 2012 09:37:05 +0800'
dd=datetime.datetime.strptime(date,'%a, %d %b %Y %H:%M:%S %z')
dd.strftime('%Y-%m-%d %H:%M:%S')
Python格式化日期时间的函数为datetime.datetime.strftime()；由字符串转为日期型的函数为：datetime.datetime.strptime()，两个函数都涉及日期时间的格式化字符串，列举如下：
%a Abbreviated weekday name
%A Full weekday name
%b Abbreviated month name
%B Full month name
%c Date and time representation appropriate for locale
%d Day of month as decimal number (01 - 31)
%H Hour in 24-hour format (00 - 23)
%I Hour in 12-hour format (01 - 12)
%j Day of year as decimal number (001 - 366)
%m Month as decimal number (01 - 12)
%M Minute as decimal number (00 - 59)
%p Current locale's A.M./P.M. indicator for 12-hour clock
%S Second as decimal number (00 - 59)
%U Week of year as decimal number, with Sunday as first day of week (00 - 51)
%w Weekday as decimal number (0 - 6; Sunday is 0)
%W Week of year as decimal number, with Monday as first day of week (00 - 51)
%x Date representation for current locale
%X Time representation for current locale
%y Year without century, as decimal number (00 - 99)
%Y Year with century, as decimal number
%z, %Z Time-zone name or abbreviation; no characters if time zone is unknown
%% Percent sign
