Python 练习实例31
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
