Question

我正在学习Python的介绍，但我遇到了一个问题。

请看一下我的剧本：

import random
secretNumber = random.randint(1,20)
print (' I am thinking of a number between 1 and 20.')

#ask the player to guess 6 times.
for guessesTaken in range (1,7):
    print ('take a guess.')
    guess = int(input())

    if guess < secretNumber:
        print ('your guess is too low')
    elif guess > secretNumber:
        print ('your guess is too high')
    else:
        break

    if guess == secretNumber:
        print ('good job! you guessed my number in ' + str(guessesTaken) + ' guesses!')
    else:
        print ('nope. the number i was thinking of was ' + str(secretNumber))

我正在尝试猜猜数字游戏。当我运行脚本时，它会问我：

猜数字
当我输入号码时，它会自动给我存储的号码而不是给我6次尝试。

如果我不清楚任何步骤，请告诉我，我会尽力在下次回答更清晰的问题！

Answer 1

以if guess == secretNumber:开头的最后一部分是循环的一部分，但您不希望在循环期间给出最终结果。而是将它放在循环之后（在它之外），这意味着你应该减少这4行代码的缩进：

import random
secretNumber = random.randint(1,20)
print (' I am thinking of a number between 1 and 20.')

#ask the player to guess 6 times.
for guessesTaken in range (1,7):
    print ('take a guess.')
    guess = int(input())

    if guess < secretNumber:
        print ('your guess is too low')
    elif guess > secretNumber:
        print ('your guess is too high')
    else:
        break

if guess == secretNumber:
    print ('good job! you guessed my number in ' + str(guessesTaken) + ' guesses!')
else:
    print ('nope. the number i was thinking of was ' + str(secretNumber))

Answer 2

最简单的解决方案是，如上所述，只需将最后一个if语句移出循环。您正在使用的语法（除了错误的缩进）非常好，这是python的一个很好的开始。但是，在python 3中，你不需要在循环内的if语句中使用else。实际上，如果满足ELSE条件你不需要做任何事情，你可以把它拿出来。
