python輸入某年某月某日，Python_今天是今年第幾天

1、傳統套路

import time

#今天的日期，年、月、日

year, month, day = time.localtime()[:3]

#每個月正常的天數

python輸入某年某月某日、day_month = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]

#閏年2月多一天

if year%400==0 or (year%4==0 and year%100!=0):

? ? day_month[1] = 29

#查看今天是今年的第幾天

if month==1:

else:

? ? print(sum(day_month[:month-1])+day)

2、Pythonic

import datetime

today = datetime.date.today()

python菜鳥教程、delta = today - datetime.date(today.year,1,1)+datetime.timedelta(days=1)

print(delta.days)

3、More Pythonic

import datetime

print(datetime.date.today().timetuple().tm_yday)
