当我不希望循环启动时

Question

我正在研究while循环的格式，我仍然不确定(我是个初学者--请原谅我)如何解决这个问题。如能提供任何帮助，将不胜感激！当用户要求提示时，我不希望“抱歉，这不是它”消息弹出--但是它仍然坚持这样做。

# 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)

hint = ''

if word == 'python':
    hint = 'snake'
if word == 'jumble':
    hint = 'jumble'
if word == 'easy':
    hint = 'opposite of hard'
if word == 'difficult':
    hint = 'opposite of easy'
if word == 'answer':
    hint = 'question'
if word == 'xylophone':
    hint = 'dingding'
# create a variable to use later to see if the guess is correct
correct = word

# create a jumbled version of the word
jumble =""
while word:
    position = random.randrange(len(word))
    jumble += word[position]
    word = word[:position] + word[(position + 1):]


count = 0

# 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 != "":
    print("Sorry, that's not it.")
    count += 1
    hint_input = input('would you like a hint')
    if hint_input == 'y':
        print(hint)
    else:
        guess = input("Your guess: ")

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

print("Thanks for playing.")

input("\n\nPress the enter key to exit.")

Answer 1

删除of :因为您总是希望从用户那里得到一个新的猜测，而不管他们是否收到了提示。

    if hint_input == 'y':
        print(hint)
    guess = input("Your guess: ")

Answer 2

您的代码工作正常，但是您需要在输入字段中输入一个包含"或'的字符串。所以输入"jumble"，而不仅仅是jumble或"y"，而不仅仅是y。

(嗯，里面有一些奇怪的逻辑，例如，在给出提示之后，它再次询问您是否需要一个提示- jus删除else以消除这种行为)，但至少它有效.

Answer 3

我复制了你的代码并运行了它。

我将输入更改为raw_input，这使输入更好。删除其他:打印后(提示)，这将解决您的问题。最后，我在“您想要一个提示吗？”之后增加了额外的空间--使它更容易阅读。
