需要解释Python中的while循环吗

Question

我是Python的初学者，我正忙于一项练习。书中有一个游戏叫做单词跳跃。我需要做的是： 改进“单词混乱”，使每个单词都有一个提示。 玩家应该能够看到提示，如果他或她卡住了。 增加一个计分系统，奖励那些不需要提示就解决混乱的玩家。在

下面是我所做的：

# Word Jumble
#
# The computer picks a random word and then "jumbles" it
# The player has to guess the original word
import random

# create a sequence of words to choose from
WORDS = ("python", "jumble", "easy", "difficult", "answer", "xylophone")

# pick one word randomly from the sequence
word = random.choice(WORDS)

# create a variable to use later to see if the guess is correct
correct = word

# create a jumbled version of the word
jumble =""
hint = "False"

while word:
    position = random.randrange(len(word))
    jumble += word[position]
    word = word[:position] + word[(position + 1):]

# start the game
print(
"""
Welcome to Word Jumble!
Unscramble the letters to make a word.
(Press the enter key at the prompt to quit.)
"""
)
print("The jumble is:", jumble)

guess = input("\nYour guess: ")
while guess != correct and guess != "":
    if guess == "hint" and word == "python":
        hint = "True"
        print("It's a snake")
        guess = input("Your guess: ")
    elif guess == "hint" and word == "jumble":
        hint = "True"
        print("It's a game")
        guess = input("Your guess: ")
    elif guess == "hint" and word == "easy":
        hint = "True"
        print("It's type of difficulty")
        guess = input("Your guess: ")
    elif guess == "hint" and word == "difficulty":
        hint = "True"
        print("It's type of difficulty")
        guess = input("Your guess: ")
    elif guess == "hint" and word == "answer":
        hint = "True"
        print("It's the opposite of question")
        guess = input("Your guess: ")
    elif guess == "hint" and word == "xylophone":
        hint = "True"
        print("Don't know WTF is that")
        guess = input("Your guess: ")
    else:
        print("Sorry, that's not it.")
        guess = input("Your guess: ")

if guess == correct:
    print("That's it! You guessed it!\n")

if hint == "False":
    print("Great! You did it without a hint")
else:
    print("Dat hint, man")

print("Thanks for playing.")
input("\n\nPress the enter key to exit.")

因此，我有了这个：

Welcome to Word Jumble!
Unscramble the letters to make a word.
(Press the enter key at the prompt to quit.)

The jumble is: jbelum

Your guess: hint
Sorry, that's not it.
Your guess: jumble
That's it! You guessed it!

Great! You did it without a hint
Thanks for playing.


Press the enter key to exit.

为什么当输入是“hint”并直接指向else子句时while循环会丢失所有内容？在

有一种方法可以简化程序：

jumble = ''.join(random.sample(word, len(word)))

Answer 2

问题是，当您进入while guess != correct and guess != "":循环时，word已经完全混乱了。因此，在该循环中的所有if和elif语句中，word永远不会等于列表中的六个单词中的一个。在

要解决此问题，请在以下语句中用correct替换word：

if guess == "hint" and correct == "python":
    hint = "True"
    print("It's a snake")
    guess = input("Your guess: ")
elif guess == "hint" and correct == "jumble":
    hint = "True"
    print("It's a game")
    guess = input("Your guess: ")
elif guess == "hint" and correct == "easy":
    hint = "True"
    print("It's type of difficulty")
    guess = input("Your guess: ")
elif guess == "hint" and correct == "difficulty":
    hint = "True"
    print("It's type of difficulty")
    guess = input("Your guess: ")
elif guess == "hint" and correct == "answer":
    hint = "True"
    print("It's the opposite of question")
    guess = input("Your guess: ")
elif guess == "hint" and correct == "xylophone":
    hint = "True"
    print("Don't know WTF is that")
    guess = input("Your guess: ")
else:
    print("Sorry, that's not it.")
    guess = input("Your guess: ")

音乐编码器是对的，解决了你的问题。为了使代码变得更好，您还需要对代码进行一些更改：

不要将字符串用于提示变量，请使用布尔值：

取而代之的是：

hint = "False"
hint = "True"

使用：

^{pr2}$

也可以重写while循环一点点

 guess = input("Your guess: ")

只有一次，不是每一次。在

另外，改变结果打印一点，因为这样它会打印提示信息，即使你输入空字符串退出游戏。在

所以它看起来像这样：

print("The jumble is:", jumble)
guess = "dummy"
while guess != correct and guess != "":
    guess = raw_input("Your guess: ")
    if guess == "hint" and correct == "python":
        hint = True
        print("It's a snake")
    elif guess == "hint" and correct == "jumble":
        hint = True
        print("It's a game")
    elif guess == "hint" and correct == "easy":
        hint = True
        print("It's type of difficulty")
    elif guess == "hint" and correct == "difficulty":
        hint = True
        print("It's type of difficulty")
    elif guess == "hint" and correct == "answer":
        hint = True
        print("It's the opposite of question")
    elif guess == "hint" and correct == "xylophone":
        hint = True
        print("Don't know WTF is that")
    else:
        print("Sorry, that's not it.")

if guess == correct:
    print("That's it! You guessed it!\n")

    if not hint:
        print("Great! You did it without a hint")
    else:
        print("Dat hint, man")

print("Thanks for playing.")
input("\n\nPress the enter key to exit.")
