爲什麼其他方法不能正常工作？

Question

我正在爲一個班製作一個簡單的hang子手遊戲。即使用戶得到正確答案，當前程序也會執行圖紙的每一步。

import turtle 
import random 
import sys 

while True: 
    list = ['report', 'beach', 'mayor', 'score', 'overeat', 'load', 'battery', 'social', 'honor', 'risk'] 

    turns = 10 
    guesses = '' 
    err = 0 

    usedw = random.choice(list) 

    wn = turtle.Screen() 
    draw = turtle.Turtle() 

    length = len(usedw) 

    print("Welcome to hangman your word is", length, "letters long.") 

    while turns > 0: 
     guess = input("Choose a character: ") 
     guesses += guess; 
     lengthr = 0 
     for char in usedw: 
      if char in guesses: 
       print (char,) 
       lengthr += 1; 
      else: 
       err += 1; 
       if err == 1: 
        draw.goto(0,0) 
        draw.down() 
        draw.goto(200,0) 
       elif err == 2: 
        draw.up() 
        draw.goto(0,0) 
        draw.down() 
        draw.goto(0,200) 
       elif err == 3: 
        draw.up() 
        draw.goto(0,200) 
        draw.down() 
        draw.goto(100,200) 
       elif err == 4: 
        draw.up() 
        draw.goto(100,200) 
        draw.down() 
        draw.goto(100,150) 
       elif err == 5: 
        draw.up() 
        draw.goto(100,100) 
        draw.down() 
        draw.circle(25)

        draw.down() 
        draw.goto(100,50) 
       elif err == 7: 
        draw.up() 
        draw.goto(75,90) 
        draw.down() 
        draw.goto(125,90) 
       elif err == 8: 
        draw.up() 
        draw.goto(100,50) 
        draw.down() 
        draw.goto(75,35) 
       elif err == 9: 
        draw.up() 
        draw.goto(100,50) 
        draw.down() 
        draw.goto(125,35) 
        print("You loose.") 
        break 
      if lengthr == length: 
       print ("You won!") 
       break 
     cont = input("Would you like to continue (y/n) ") 
     if cont == 'y': 
      print("Alright!") 
     else: 
      print("Thanks for playing!") 
      break

Answer 2

技術問題 是在你在/正確確定邏輯：

for char in usedw: 
    if char in guesses: 
     print (char,) 
     lengthr += 1; 
    else: 
     err += 1; 
     if err == 1: 
      ... 

的爲通過字的字符迭代。例如，如果單詞「過度」，則對於每個猜測，您將執行這個循環七個次。即使玩家猜出最好的「e」，你也會對他/她錯誤地猜出字母「ovrat」，並畫出五個男孩的部分。

REPAIR

首先，你要確定最近猜測字母是否在詞任何地方：

if guess in usedw: 
    print (char,) 
    lengthr += 1; 
else: 
    err += 1; 
    if err == 1: 
    ... 

還有其他的問題及改進措施，但這應該讓你感動。
