题目：输入某年某月某日，判断这一天是这一年的第几天？
自己的代码如下：
1 # -*- coding: utf-8 -*- 2 """ 3 Created on Fri Oct 4 22:08:42 2019 4 5 @author: Franz 6 """ 7 8 def leap(year): 9 index = False 10 if year % 400 == 0: 11 index = True 12 else: 13 if year % 4 == 0 and year % 100 !=0: 14 index = True 15 return index 16 17 year = int(input(‘please input the year you want to check: ‘)); 18 month = int(input(‘please input the month you want to check: ‘)); 19 day = int(input(‘please input the day you want to check: ‘)) 20 21 mon_days = [0,31,59,90,120,151,181,212,243,273,304,334]; 22 if not leap(year): 23 days = mon_days[month-1]+day; 24 else: 25 if month >= 2: 26 days = month_days[month-1]+1+day 27 else: 28 days = mon_days[month-1]+day; 29 30 print(‘it is the %dth day.‘ % days)
分析：代码写的很渣，其中很多条件判断可以合到一个if语句中进行判断，对于代码优先级还欠考虑。优点在于领悟到了闰年月份与非闰年月份天数的差异，并根据一个数组实现月份的查询。
如下是标准答案（python-2.7x）。
#!/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
