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。。
程序源代码：
实例(Python2.x)
#!/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')
实例(Python3.x)
#!/usr/bin/python3 letter = input("please input:")#while letter != 'Y':if letter == 'S': print ('please input second letter:') letter = 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 = 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
