28):题目:请输入星期几的第一个字母来判断一下是星期几,如果第一个字母一样,则继续判断第二个字母。
程序分析:用情况语句比较好,如果第一个字母一样,则判断用情况语句或if语句判断第二个字母。
#!/usr/bin/python # -*- coding: UTF-8 -*- letter = raw_input("please input:") #while letter != ‘Y‘: if letter == ‘S‘: print (‘please input second letter:‘) letter = raw_input("please input:") if letter == ‘a‘: print (‘Saturday‘) elif letter == ‘u‘: print (‘Sunday‘) else: print (‘data error‘) elif letter == ‘F‘: print (‘Friday‘) elif letter == ‘M‘: print (‘Monday‘) elif letter == ‘T‘: print (‘please input second letter‘) letter = raw_input("please input:") if letter == ‘u‘: print (‘Tuesday‘) elif letter == ‘h‘: print (‘Thursday‘) else: print (‘data error‘) elif letter == ‘W‘: print (‘Wednesday‘) else: print (‘data error‘)
以上实例输出结果为:
please input:S please input second letter: please input:a Saturday
#!/usr/bin/python # -*- coding: UTF-8 -*- import re def judge(first,list): li=[] first = first.upper() for a in list: if re.match(first,a): li.append(a) if len(li)==1: print li[0] else: second=raw_input(‘请输入第二个字母:‘) for b in li: if re.match(first+second,b): print b list=[‘Monday‘,‘Tuesday‘,‘Wednesday‘,‘Thursday‘,‘Friday‘,‘Saturday‘,‘Sunday‘] first=raw_input(‘请输入第一个字母:‘) judge(first,list)
Python3 测试实例:
#!/usr/bin/python3 weeklist = {‘M‘: ‘Monday‘,‘T‘: {‘u‘: ‘Tuesday‘,‘h‘:‘Thursday‘}, ‘W‘: ‘Wednesday‘, ‘F‘:‘Friday‘,‘S‘:{‘a‘:‘Saturday‘,‘u‘:‘Sunday‘}} sLetter1 = input("请输入首字母:") sLetter1 = sLetter1.upper() if (sLetter1 in [‘T‘,‘S‘]): sLetter2 = input("请输入第二个字母:") print(weeklist[sLetter1][sLetter2]) else: print(weeklist[sLetter1])
Python3实例,使用递归函数实现,对字符相同的个数没有限制:
#!/usr/bin/env python3 week=[‘Monday‘,‘Tuesday‘,‘Wednesday‘,‘Thursday‘,‘Friday‘,‘Saturday‘,‘Sunday‘] def find(s,week): a = input("please input a letter\n") s=s+a #print(s) result=[] for i in week: if i.startswith(s): result.append(i) #print (result) if len(result)==1: return result else: return find(s,result) s=‘‘ print(find(s,week))
