python之猜号机 : Please Review and Make it More Pythonic

我正在学习 python，这是一个简单的程序，我写道:

def guesser(var, num1,possible): 
    if var == 'n': 
        cutoff = len(possible)/2 
        possible = possible[0:cutoff] 
        cutoff = possible[len(possible)/2] 
        #print possible 
 
        if (len(possible) == 1): 
             print "Your Number is:", possible 
        else: 
            var = raw_input("Is Your Number Bigger Than %s? (y/n): " %cutoff) 
            guesser(var, cutoff,possible) 
 
 
    elif var == 'y': 
        cutoff = len(possible)/2 
        possible = possible[cutoff:len(possible)] 
        cutoff = possible[len(possible)/2] 
        #print possible 
        #print cutoff 
 
       if (len(possible) == 1): 
           print "Your Number is:", possible 
       else: 
            var = raw_input("Is Your Number Bigger Than %s? (y/n): " %cutoff) 
            guesser(var, cutoff,possible) 
 
 
    else: 
        var = raw_input("Is Your Number Bigger Than 50? (y/n): ") 
        guesser(var, 50, possible) 
 
possible = [] 
possible = range(1,101) 
 
guesser('a', 50, possible) 

请您参考如下方法:

通常我会尝试帮助您编写代码，但是您方式太复杂了，我认为您查看一些代码会更容易。

def guesser( bounds ): 
    a, b = bounds 
    mid = ( a + b ) // 2 
 
    if a == b: return a 
 
    if input( "over {0}? ".format( mid ) ) == "y": 
        new_bounds = ( mid, b ) 
    else: 
        new_bounds = ( a, mid ) 
 
    return guesser( new_bounds ) 

在深入研究之前，您应该从抽象的角度考虑您的算法将如何工作。

编辑:以简洁为代价简化了代码。
