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()))函數來格式化日期。如果我們要獲取當前日期,可以利用時間函數time()來獲取。
python 格式化日期到毫秒
可以參考下面的代碼:
一、代碼一:
importdatetime
print(datetime.datetime.now().microsecond*1e-3)
二、代碼二:
importdatetime
now=datetime.datetime.now()
printnow.strftime(“%Y%m%d%H%M%S”)
擴展資料:
python函數
hasattr(obj,name)查看一個obj的namespace中是否有name
getattr(obj,name)得到一個obj的namespace中的一個name
setattr(obj,name,value)為一個obj的namespace中的一個name指向vale這個object
delattr(obj,name)從obj的namespace中刪除一個name

python,格式化時間實例,求
對於像’Wed, 11 Apr 2012 09:37:05 +0800’的時間格式化可如下解:
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格式化日期時間的函數為datetime.datetime.strftime();由字符串轉為日期型的函數為:datetime.datetime.strptime(),兩個函數都涉及日期時間的格式化字符串,列舉如下:
%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
