Python如何獲得程序運行時間的格式化顯示
(1)在程序啟動時獲得當前時間:
recordTime = time.time()
(2)同時獲得當前時間的格式化串:
startTime = time.strftime(“%H%M%S”)
(3)在主循環中按秒進行判斷:
timeGap = time.time() – recordTime
if timeGap = 1: #這是按1秒設置的,可以根據實際需要設置
recordTime += timeGap
showTime_String = get_lapseTime(startTime, time.strftime(“%H%M%S”))
(4)函數:
def get_lapseTime(aTime, bTime):
aNum = 3600 * int(aTime[:2]) + 60 * int(aTime[2:4]) + int(aTime[-2:])
bNum = 3600 * int(bTime[:2]) + 60 * int(bTime[2:4]) + int(bTime[-2:])
gapH = (bNum – aNum) // 3600
gapM = ((bNum – aNum) % 3600) // 60
gapS = ((bNum – aNum) % 3600) % 60
gapTime = “%02d:%02d:%02d”%(gapH,gapM,gapS)
return(gapTime)
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();由字元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元串,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
