问题及答案实例四，关于日期的简单练习
Python练习题问题如下：
简述：要求输入某年某月某日
提问：求判断输入日期是当年中的第几天？
#!/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 #www.iplaypy.com 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
上面是参考答案，以下我的练习，加了一些格式校验，当然写成类可能更好看
此题，实验出来range（0）后 面不执行，不会抛出异常
1 #!/usr/bin/env python 2 #coding:utf8 3 import time,datetime 4 import os 5 6 days = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] 7 def ReadDate(): 8 print "Please input a date string like 20170102 or 2017-01-02" 9 Dateis = raw_input("Date is:") 10 Dateis = Dateis.replace(‘-‘,‘‘) #加工成20170102 11 print Dateis 12 return Dateis 13 14 def Datesplite(Dateis): #返回年月日列表 15 print Dateis 16 if len(Dateis) != 8: 17 print ‘Wrong input!‘ 18 else: 19 try: 20 Year = int(Dateis[0:4]) 21 Moon = int(Dateis[4:6].lstrip(‘0‘)) 22 Day = int(Dateis[6:8].lstrip(‘0‘)) 23 except: 24 print "Format is Wrong!" 25 return [Year,Moon,Day] 26 27 def Datecount(list_in): 28 print list_in 29 cday = 0 30 if list_in[0] %4 == 0 and list_in[1] > 2: 31 days[1] =days[1]+1 32 for i in range(list_in[1]-1): #当range（0）时，这个后面不执行 33 print days[i] 34 cday += days[i] 35 cday +=list_in[2] 36 print cday,‘th‘ 37 38 ‘‘‘ 一般调用顺序 39 inputdate = ReadDate() 40 splipdate = Datesplite(inputdate) 41 Datecount(splipdate) 42 ‘‘‘ 43 44 Datecount(Datesplite(ReadDate()))
