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':ifletter == 'S': print('please input second letter:') letter = raw_input("please input:") ifletter == 'a': print('Saturday') elifletter == 'u': print('Sunday') else: print('data error') elifletter == 'F': print('Friday') elifletter == 'M': print('Monday') elifletter == 'T': print('please input second letter') letter = raw_input("please input:") ifletter == 'u': print('Tuesday') elifletter == 'h': print('Thursday') else: print('data error') elifletter == 'W': print('Wednesday')else: print('data error')
实例(Python3.x)
#!/usr/bin/python3letter = input("please input:")#while letter != 'Y':ifletter == 'S': print('please input second letter:') letter = input("please input:") ifletter == 'a': print('Saturday') elifletter == 'u': print('Sunday') else: print('data error') elifletter == 'F': print('Friday') elifletter == 'M': print('Monday') elifletter == 'T': print('please input second letter') letter = input("please input:") ifletter == 'u': print('Tuesday') elifletter == 'h': print('Thursday') else: print('data error') elifletter == '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
