python - 为什么其他的不能正常工作？

Question

我正在为类(class)制作一个简单的刽子手游戏。当前的程序会执行绘图的每一步，即使用户得到了正确的答案。

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)
                elif err == 6:
                    draw.up()
                    draw.goto(100,100)
                    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
            sys.exit()

问题 是在你的判断逻辑中:

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

for 遍历单词的字符。例如，如果单词是“overeat”，则每次猜测都会执行此循环七次。即使玩家猜对了“e”，您也会指控他/她猜错了字母“ovrat”，并抽出了五个男孩部件。

修复

首先，您必须确定最近猜到的字母是否在单词任何地方中:

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

还有其他问题和改进，但这应该会让您前进。
