Python的hang子手不透露字母

Question

我正在處理的一個version子手的Python版本，工作的.txt文件的單詞列表。出於某種原因，在初次玩遊戲後的劇本中，腳本不會顯示某些字母。其他一切都按我想要的方式工作，或多或少。

我的代碼：

import random 

wordlist = open("wordlist.txt").read().split() 
word = random.choice(wordlist) 
strikes = 0 
hidden_letters = [] 
alphabet = "abcdefghijklmnopqrstuvwxyz" 
guesses = [] 

def new_word(): 
    global word 
    global guesses 
    word = random.choice(wordlist) 
    for letter in set(word): 
     if letter in alphabet: 
      hidden_letters.append(letter) 
    guesses = [] 

def current_progress(): 
    for letter in word: 
     if letter in hidden_letters: 
      print '_', 

     elif letter == ' ': 
      print ' ', 

     else: 
      print letter, 
    print "\n" 

def play_again(): 
    global strikes 
    print "Would you like to play again?" 
    answer = raw_input("y/n: ") 
    if answer == "y": 
     strikes = 0 
     main() 
    elif answer == "n": exit(0) 
    else: 
     print "That's not a valid answer." 
     play_again() 

def letter_in_word(x): 
    global strikes 
    global hidden_letters 
    if x in word: 
     hidden_letters.remove(x) 
     print "That letter is in the word." 
     current_progress() 
     if hidden_letters == []: 
      print "You win!" 
      play_again() 
     else: 
      print "You have %d strike(s)." % strikes 

    elif not x in word: 
     print "That letter is not in the word." 
     current_progress() 
     strikes = strikes + 1 
     print "You have %d strike(s)." % strikes 

def main(): 
    new_word() 
    current_progress() 
    global strikes 
    while strikes < 6 and not hidden_letters == []: 
     print "Guess a letter. \n Letters that have been already guessed are:", guesses 

     guess = raw_input("> ") 

     if guess in alphabet and len(guess) == 1: 
      if not guess in guesses: 
       guesses.append(guess) 
       letter_in_word(guess) 

      else: 
       print "You've already guessed that letter. Pick another." 
       current_progress() 
       print "You have %d strikes." % strikes 

     else: 
      print "Sorry, that's not a valid guess." 
      current_progress() 
      print "You have %d strikes." % strikes 

    if strikes == 6: 
     print "Oop! You lose." 
     print "The answer was:", word 
     play_again() 

print "Welcome to Hangman!" 
print "Six strikes and you lose." 
print "----------"  
main() 

Answer 1

您的問題：當玩家猜測存在於當前詞和前一個字的信，但前一個字沒有猜到（玩家失去了遊戲） ，該字母仍然在hidden_letters列表中，因爲remove(x)僅刪除該字母的第一個實例。換句話說，在某些執行過程中，您的列表包含兩個相同的字母，這違反了您的代碼的隱含要求。在添加新單詞的字母之前，您可以通過在您的new_word()函數中添加hidden_letters = []來解決此問題。

從Python tutorial（重點煤礦）：

list.remove(x)

中值爲X列表中刪除第一項。如果沒有這樣的項目，則是錯誤 。

Answer 2

或者說，我想你可以對new_word()的beggining添加語句

del hidden_letters[:] 

。它將清除hidden_letters列表。
