温习PYTHON语法

看WEBPY的源码结构有点晕，原来很多语法结构都忘了，继承之些。

再看A BYTE OF PYTHON。慢慢补。。

number = 23
guess = int(raw_input('Enter an integer : '))

if guess == number:
    print 'Congratulations, you guessed it.'
    print '(but you do not win any prizes!)'
elif guess < number:
    print 'No, it is a little higher than that.'
else:
    print 'No, it is a little lower than that.'
print 'Done!'
