elif语句出错

Question

这是我正在阅读的Python书中的一个例子.当我尝试运行程序时出现错误,当我检查错误的代码时elif会以红色突出显示.我在Python 2.5中编程.

import random

secret = random.randint(1, 99)
guess = 0
tries = 0

print "It is a number between 1 and 99. I'll give you six tries. "

while guess != secret and tries < 6:
    guess = input("What's your guess? ")
    if guess < secret:
        print "Too low!"
        elif guess > secret:
            print "Too high"
            tries = tries + 1
            if guess == secret:
                print "Correct! You found my secret!"
                else:
                    print "No more guesses! Better luck next time!"
                    print "The secret number was", secret

Python是缩进敏感的.

import random

secret = random.randint(1, 99)
guess = 0
tries = 0

print "It is a number between 1 and 99. I'll give you six tries. "

while guess != secret and tries < 6:
    guess = input("What's your guess? ")
    if guess < secret:
        print "Too low!"
    elif guess > secret:
        print "Too high"
        tries = tries + 1
    elif guess == secret:
        print "Correct! You found my secret!"
    else:
        print "No more guesses! Better luck next time!"
        print "The secret number was", secret 

编辑:我知道这里仍有bug,比如tries = tries + 1应该在代码中的其他地方.但是这个版本至少没有给出语法错误.
