比較時相同值的兩個整數值表示它們不相等

我最近學了一點python。我試圖在框架小部件上制作一個猜數字游戲。按下亂數按鈕以生成亂數。Enter 按鈕然后從輸入框中獲取輸入并與生成的亂數進行比較。為了測驗它，程式會顯示一個標簽，顯示生成的亂數。當我輸入與生成的數字相同的數字時，它說它不相等。它唯一一次說它相等是當我輸入 0（零）時。我還有一些行告訴我這些值是什么型別，只是為了確保我比較相同的型別。

from random import randint
from tkinter import *

root = Tk()
root.title('Guess Number Final')
root.geometry('500x500')



directionFrame = Frame(root, width = 200, height = 200, highlightbackground = 'red', 
highlightthickness = 3)
directionFrame.grid(row = 0, column = 0, padx = 20, pady = 20, ipadx = 20, ipady = 20)

randomNum = IntVar()
newguessInt = IntVar()

def randomize():

     randomNum = randint(0,10)
     randomStr.set(randomNum)


def enterGuess():

    newguessInt = int(number_input.get())

    newRandom = randomNum.get()

    if (newguessInt == newRandom):

        guess_var.set('Your guess is right.')

    else:

         guess_var.set('Your guess is wrong.')


    guess_str.set(type(newguessInt))
    random_str.set(type(newRandom))

##### Random Button #####

randomBtn = Button(directionFrame, text = 'Random Number', command = randomize)
randomBtn.pack()


##### Random Variable #####

randomStr = StringVar()
randomStr.set('Number')

##### Guess Variable #####

guess_var = StringVar()
guess_var.set('Your guess is...')


##### typeGuessVariable #####

guess_str = StringVar()
guess_str.set('Type')

##### randomNumVariable #####

random_str = StringVar()
random_str.set('Type')


##### Random Label #####

randomLbl = Label(directionFrame, textvariable = randomStr)
randomLbl.pack()


##### Number Entry Box #####

number_input = Entry(directionFrame)
number_input.pack()

##### Enter Button #####

enterBtn = Button(directionFrame, text = 'Enter Guess', command = enterGuess)
enterBtn.pack()

##### Your Guess Label #####

yourGuessLbl = Label(directionFrame, textvariable = guess_var)
yourGuessLbl.pack()


##### GuessInt Label ######

guessIntLbl = Label(directionFrame, textvariable = guess_str)
guessIntLbl.pack()

##### Random Label ######
randomNumLbl = Label(directionFrame, textvariable = random_str)
randomNumLbl.pack()

mainloop()

您已經宣告了許多 tkinter 變數，使您混淆使用錯誤的變數進行比較。

實際上只使用兩個 tkinter 變數就足夠了：

• randomNum 對于隨機生成的數字
• guessNum 用于用戶猜測號碼

from random import randint
from tkinter import *


root = Tk()
root.title('Guess Number Final')
root.geometry('500x500')

directionFrame = Frame(root, width=200, height=200, highlightbackground='red', highlightthickness=3)
directionFrame.grid(row=0, column=0, padx=20, pady=20, ipadx=20, ipady=20)

randomNum = StringVar(value='Number')
guessNum = StringVar(value='')


def randomize():
    randomNum.set(randint(0,10))


def enterGuess():
    ok = randomNum.get() == guessNum.get().strip()
    resultLabel['text'] = f'Your guess is {"right" if ok else "wrong"}.'


##### Random Button #####

randomBtn = Button(directionFrame, text='Random Number', command=randomize)
randomBtn.pack()

##### Random Label #####

randomLbl = Label(directionFrame, textvariable=randomNum)
randomLbl.pack()

##### Number Entry Box #####

number_input = Entry(directionFrame, textvariable=guessNum)
number_input.pack()

##### Enter Button #####

enterBtn = Button(directionFrame, text='Enter Guess', command=enterGuess)
enterBtn.pack()

##### Result Label #####
resultLabel = Label(directionFrame, text='Your guess is ...')
resultLabel.pack()

mainloop()

這一行：

randomNum = randint(0,10)

創建一個新的區域變數randomNum并將其分配給常規 Pythonint值。randomNum外部作用域中的原始IntVar值仍然是默認值為零。我認為你想做的是：

randomNum.set(randint(0, 10))

即設定IntVar您創建指向一個新的隨機整數。
