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
