Question

我正在尝试在python中创建一个GUI程序来生成随机的彩票号码。我想有一个菜单栏来选择Powerball或MegaMillion。选择后，会有按钮让用户选择要显示的门票数量。但我无法使该方法有效。我想在单击按钮时显示不同的数字列表行，但它确实显示了任何内容。我还没有完成，因为它没有工作。我是Python和编程的新手，请帮忙！谢谢！

from tkinter import *
import random

class lotteryNum:
    def __init__(self):
        window=Tk()
        window.title("Lottery Number Generator")

        menubar = Menu(window)
        window.config(menu=menubar)

        self.pbLst = [x for x in range(1,70)]
        self.pbLst2=[x for x in range(1,27)]
        self.mmLst = [x for x in range(1,76)]
        self.mmLst2=[x for x in range(1,16)]
        self.usingLst=["*"]*6



        #Type Menu
        typeMenu = Menu(menubar, tearoff = 0)
        menubar.add_cascade(label = "Which Lottery", menu = typeMenu)
        typeMenu.add_command(label="Powerball", command= self.powerBall)
        typeMenu.add_command(label="Mega Milion", command= self.megaMillion)


        #Exit menu
        exitmenu = Menu(menubar, tearoff = 0)
        menubar.add_cascade(label = "Exit", menu = exitmenu)
        exitmenu.add_command(label = "Quit", command = window.quit)

        #Welcome label
        Label(window, text="Welcome to Lottery Generator!").pack()

        frame=Frame(window)
        frame.pack()

        #Text Label
        self.showResults = StringVar()
        Label(frame, text=self.showResults).pack()




        Button(window, text="$2", command=self.runLottery()).pack(side=LEFT)

        window.mainloop()


    def powerBall(self):
        # random.shuffle(self.pbLst)
        # random.shuffle(self.pbLst2)
        self.usingLst=self.pbLst
        self.usingLst2=self.pbLst2

    def megaMillion(self):

        # random.shuffle(self.mmLst2)
        self.usingLst=self.mmLst

    def runLottery(self):
        random.shuffle(self.usingLst)
        random.shuffle(self.usingLst2)
        self.usingLst[:5].extend(self.usingLst2[0])
        self.showResults.set(self.usingLst)





lotteryNum()

Answer 1

我认为如果您更改此行，您的代码应该可以使用：

Label(frame, text=self.showResults).pack()

到此：

Label(frame, textvariable=self.showResults).pack()

完成的代码只是让有兴趣的人知道我在这里尝试做什么。

        self.mmLst2=[x for x in range(1,16)]
        self.usingLst=[0]*6
        self.usingLst2=[0]*6

        #Type Menu
        typeMenu = Menu(menubar, tearoff = 0)
        menubar.add_cascade(label = "Which Lottery", menu = typeMenu)

lotteryNum()

Answer 3

打印self.usingLst以确保它包含某些内容，并

self.showResults=Label(frame, text="no choices made")
self.showResults.pack()

然后在runLottery

self.showResults["text"]="\n".join(self.usingLst)

如何在Tkinter中显示字符串变量？
