Question

我为一个介绍python类的最终项目创建了一个Hangman类和一个HangmanGUI类。如果我犯了业余错误，我很抱歉，但我没有很强的编码背景。每次我的合作伙伴和我运行GUI类时，都会收到此错误：

    self.__letterVar.set(self.__ans.getAnswer())
TypeError: set() missing 1 required positional argument: 'value'

这是刽子手类：

from random import *

FOUR = 4

class Hangman:

  # --------------------------------------------------------------------------
  # Constructor
  def __init__(self):
    self.__theWord = ''
    self.__indexList = []
    self.__answer = '_ _ _ _ _ _'
  # ---------------------------------------------------------------------------
  # Accessors
  def getTheWord(self):
    return self.__theWord
  def getIndexList(self):
    return self.__indexList
  def getAnswer(self):
    return self.__answer
  def startFruit(self):
    randNumber = randint(0,FOUR)
    fruit = open("fruits.txt", 'r')
    fruitList = fruit.read().splitlines()
    self.__theWord = fruitList[randNumber]
    return self.__theWord
  def startVege(self):
    randNumber = randint(0,FOUR)
    vege = open("veges.txt", 'r')
    vegeList = vege.read().splitlines()
    self.__theWord = vegeList[randNumber]
    return self.__theWord
  def startName(self):
    randNumber = randint(0,FOUR)
    name = open("names.txt", 'r')
    nameList = name.read().splitlines()
    self.__theWord = nameList[randNumber]
    return self.__theWord
  # --------------------------------------------------------------------------
  # Mutators
  def find(self, answerWord, inputLetter):
    if inputLetter in answerWord:
      self.__indexList = [index for index, letter in enumerate(answerWord) if letter ==         inputLetter]
    else:
      self.__indexList = []

  def set (self, inputLetter):
    newString = ""
    textList = list(self.__answer)
    self.__indexList = self.getIndexList()
    location = self.__indexList
    for aNum in location:
        textList[aNum * 2] = inputLetter 
        newString = ''.join(textList)
        self.__answer = newString

  def reset(self):
    self.__answer = '_ _ _ _ _ _' 
  # --------------------------------------------------------------------------
  # toString()
  def__str__(self):
    return "Current answer is: %s" % self.__answer

'''
def main():
  game = Hangman()
  keyWord = game.startFruit()
  letter = input("enter letter")
  while letter:
    game.find(keyWord, letter)
    game.set(letter)
    print(game)
    letter = input("enter letter")
main()
'''

在同一个文件夹中有几个名为Fruits，Veges和Names的文件，每个文件在各自的类别中有大约5-6个六个字母的单词。我想让程序打开并读取文件并在列表中随机提取一个单词。

我们测试了我们的hangman类，我们认为它工作正常，但我认为我们的问题源于我们的HangmanGUI类。

from tkinter import *
from random import *
from hangman import *

FOUR = 4 
class HangmanUI(Frame):

  def __init__(self):
    Frame.__init__(self)
    self.master.title("Hangman")
    self.grid()
    self.__label = Label(self, text = "Let's play Hangman!")
    self.__label2 = Label(self, text = "Please choose a category!")
    self.__label2.grid(row = 1, column = 0)
    self.__buttonPane = Frame(self)
    self.__buttonPane.grid(row = 2, column = 0)
    # created a model of the hangman class
    self.__ans = Hangman()
    self.__fruitButton= Button(self.__buttonPane, text = 'Fruits', command =     self.startFruit)
    self.__nameButton = Button(self.__buttonPane, text = 'Names' , command = self.startName)
    self.__vegeButton = Button(self.__buttonPane, text = 'Veges', command = self.startVege)
    self.__fruitButton.grid(row = 2, column = 0)
    self.__vegeButton.grid(row = 2, column = 1)
    self.__nameButton.grid(row = 2, column = 2)
    self.__label.grid(row = 0 , column = 0)
    #to change later so if shuffles images 1-10 with each error (for loop)
    self.__image = PhotoImage(file = "0.gif")
    self.__imageLabel = Label(self, image = self.__image)
    self.__imageLabel.grid(row = 3, column = 0)
    self.__letterLabel = Label(self, text = "Please submit a letter to play!")
    # instead of the submit button, tried using enter instead for now
    self.__letterVar= StringVar
    #self.__letterEntry = Entry(self, textvariable = self.__letterVar) # commented out this line, maybe i shouldn't have?
    self.__letterEntry = Entry(self, width = 10)
    self.__letterEntry.bind('<Return>', self.set)
    self.__letterLabel.grid(row = 4, column = 0)
    self.__letterEntry.grid(row = 5, column = 0)

    self.__value = Label(self, textvariable = self.__letterVar)
    self.__value.grid(row= 6, column = 0)


    #creates nested frame 
    self.__letterPane = Frame(self)
    self.__letterPane.grid(row = 7, column = 0)
    self.__letter1 = Label(self.__letterPane, text = '_  _  _  _  _  _')
    self.__letter1.grid(row = 7, column = 0)
  def startFruit(self):
    self.__ans.startFruit()
  def startVege(self):
    self.__ans.startVege()
  def startName(self):
    self.__ans.startName()
  def set(self,event):
    guessWord = self.__ans.getTheWord()
    entryLetter = self.__letterEntry.get()
    self.__ans.find(guessWord, entryLetter)
    newValue = self.__letterEntry.get()
    self.__ans.set(newValue)
    # display new value in letterVar
    # this is where the program crashes
    self.__letterVar.set(self.__ans.getAnswer())
    # invoke delete() to clear entry box
    self.__letterEntry.delete(0,END)


def main():
  HangmanUI().mainloop()
main()

对于长码，很抱歉，这是我第一次在这里发帖，我们都非常紧张，因为我们大学的决赛周，我们一直疯狂地试图把它放在一起。我们都不是复合科学大学，所以这是一个相当困难的过程。

我们不确定如何调用Hangman类并使用GUI中Hangman类的方法。截至目前，我们已收到上述错误，而且我们不确定如何修复错误。程序在def set（self，event）的GUI类结束时崩溃：

如果有人能提供任何见解和提示，那将非常感谢！

Answer 1

您需要__letterVar StringVar {em}

self.__letterVar = StringVar()

否则其上的set()方法未绑定，并且不会获得自动self第一个参数。

您的代码将其指定为类，而不是新实例。

Python中的Hangman游戏（GUI）给出了TypeError
