Python 練習(xí)實(shí)例4
Python 100例題目：輸入某年某月某日，判斷這一天是這一年的第幾天？
程序分析：以3月5日為例，應(yīng)該先把前兩個月的加起來，然后再加上5天即本年的第幾天，特殊情況，閏年且輸入月份大于2時需考慮多加一天：
程序源代碼：
實(shí)例(Python 2.0+)
#!/usr/bin/python
# -*- coding: UTF-8 -*-
year = int(raw_input('year:n'))
month = int(raw_input('month:n'))
day = int(raw_input('day:n'))
months = (0,31,59,90,120,151,181,212,243,273,304,334)
if 0 < month <= 12:
sum = months[month - 1]
else:
print 'data error'
sum += day
leap = 0
if (year % 400 == 0) or ((year % 4 == 0) and (year % 100 != 0)):
leap = 1
if (leap == 1) and (month > 2):
sum += 1
print 'it is the %dth day.' % sum
以上實(shí)例輸出結(jié)果為：
year: 2015 month: 6 day: 7 it is the 158th day.其他擴(kuò)展
