Question

背景：我的Tkinter应用程序中有一个小功能，它可以将列表中的两个随机值随机化，并将它们打印到GUI。但是我正在努力获得具有随机值的正确图像（团队徽标）。

目标：是随机的球队名称（来自28个球队），GUI也应显示球队徽标。按下按钮“ RANDOM”，它会生成Team1和Team2，并且两者之间都应带有徽标。

我已经进行了以下研究：我有时间回答这个问题，但是我无法弄清楚。这个骰子游戏可以做到，但我需要两个值而不是一个，并且我的列表中充满了字符串。

import random
import tkinter as tk
from PIL import ImageTk, Image

 # Use a class that hold all Team data
class Team():
   def __init__(self, name, img_filename):
    self.name = name
    self.img_filename = img_filename

   @property
   def image(self):
    # TODO: Open image file and return .PhotoImage object
    team_logo = Image.open("%s.jpg" % (self.img_filename))
    render = ImageTk.PhotoImage(team_logo)
    self.img_filename.image = render
    return self.img_filename

   #This is how the class prints
   def __str__(self):
    return "Name: {} Image:{}".format(self.name, self.img_filename)


class MainWindow(tk.Frame):
      def __init__(self, parent, *args, **kwargs):
       tk.Frame.__init__(self, parent,  *args, **kwargs)
       root.geometry("700x450")
       text_1 = tk.Label(text="VS", fg="red", anchor="center")
       text_1.place(relx=.5, rely=.5, anchor="center")
       text_2 = tk.Label(text="RANDOM GAME", fg="green", anchor="n")
       text_2.pack(side="top")

       # Button for randomize
       self.parent = parent
       self.frame = tk.Frame(self.parent)
       self.randomButton = tk.Button(self.frame, text = 'RANDOM', 
       command=self.genRanTeam)
       self.randomButton.pack(side="bottom")
       self.frame.pack(side="bottom")

       self.home_name = tk.StringVar()
       self.visitor_name = tk.StringVar()

       if 0: # TODO: Implement Team.image
           # Images, I should somehow use this with home/visitor label?
           # Yes, look at TODO in def genRanTeam(...

           load = Image.open("%s.jpg" % (self.home.image))
           render = ImageTk.PhotoImage(load)
           # ONLY, if you decide to use OWN Label for Image
           # What you suggest for this? So if I decide to only use home/visitor labels, I don't need next 4 lines of code (after this text?)
           self.team_logo = tk.Label(parent, image=render)
           self.team_logo.image = render
       else:
           self.team_logo = None


       # Home team
       self.home_label = tk.Label(Image = self.team_logo, textvariable=self.home_name) 
       self.home_label.pack(side="left")
       # Visitor team
       self.visitor_label = tk.Label(Image = self.team_logo, textvariable=self.visitor_name) 
       self.visitor_label.pack(side="right")

       self.__init__Teams()

      # Hold this in a own function for brevity
      def __init__Teams(self):
        self.teams = [Team('Chicago Fire', 'chicago'), Team('New York \
        Red Bulls', 'newyork'), Team('Philadelphia Union', 'phila'), 
        Team('Toronto FC', 'toronto')]
        # Init defaults
        self.home = self.teams[0]
        self.visitor = self.teams[0]

      def genRanTeam(self):
        # Use the initalized Teams from MainWindow..__init__
        self.__init__Teams()
        self.home = random.choice(self.teams)
        self.visitor = None
        # Loop while home == visitor
        while self.visitor is None or self.home.name is self.visitor.name:
         self.visitor = random.choice(self.teams)

        self.home_name.set(self.home.name)
        self.visitor_name.set(self.visitor.name)   

        # TODO: Configure .team_label with Team.image
        # self.home_label.configure(image=self.home.image)
        self.home_label.configure(image=self.home.image)
        self.visitor_label.configure(image=self.visitor.image)

if __name__ == "__main__":
         root = tk.Tk()
         main = MainWindow(root)
         main.pack(side="top", fill="both", expand=True)
         root.mainloop()

现在，当我按下RANDOM按钮时，它将对列表中的变量x和y正确地随机赋值。

我的文件夹项目/图像中也有28张图像。所有图像都是“ team_name.jpg”

问题1：如何循环列出并匹配团队名称和徽标？

感谢所有帮助，并且一些代码复审也将非常有用！（SO中的第一个问题！）

Answer 1

评论：实施Team.image

运行您的Team.image会给我：

self.img_filename.image = render
AttributeError: 'str' object has no attribute 'image'

您不能向内置str对象添加新属性。这将起作用，更改为：

self.render = ImageTk.PhotoImage(team_logo)
return self.render

评论：我需要为团队形象制作另一个tk.Label吗？

不需要这样做，这取决于您所需的布局。
从一个开始tk.Label(self, image=image, textvariable=name)
看起来像：

评论：self.visitor是否可以显示团队+徽标？

显示任何内容不是class Team()的功能，而是tk.Lable(...的工作。

问题：列表中的两个随机值必须与图片匹配

这种方法不要使用两个列表，它在一个类中定义了两个值（团队名称，团队形象）。因此，不需要匹配。
例如：

# Use a class that hold all Team data
class Team():
    def __init__(self, name, img_filename):
        self.name = name
        self.img_filename = img_filename

    # This is how the class prints
    def __str__(self):
        return "Name: {} Image:{}".format(self.name, self.img_filename)

class MainWindow(tk.Frame):
    def __init__(self, parent, *args, **kwargs):

        # Up to 28 teams - Defined in __init__ only once
        # Create a list with all Teams using class Team
        self.teams = [Team('Chicago Fire', 'logo1.jpg'), Team('New York Red Bulls', 'logo2.jpg'), Team('Philadelphia Union', 'logo3.jpg'), Team('Toronto FC', 'logo4')]
        # Init defaults
        self.home = self.teams[0]
        self.visitor = self.teams[0]

    def genRanTeam(self):
        # Use the initalized Teams from __init__
        self.home = random.choice(self.teams)

        self. visitor = None
        # Loop while home == visitor
        while self.visitor is None or self.home is self.visitor:
            self.visitor = random.choice(self.teams)

if __name__ == "__main__":
    import time

    root = tk.Tk()
    main = MainWindow(root)
    for _ in range(3):
        main.genRanTeam()
        print("home:{} :\tvisitor:{}".format(main.home, main.visitor))
        time.sleep(1)

输出：

home:Name: Toronto FC Image:logo4 : visitor:Name: Chicago Fire Image:logo1.jpg
home:Name: New York Red Bulls Image:logo2.jpg : visitor:Name: Toronto FC Image:logo4
home:Name: Toronto FC Image:logo4 : visitor:Name: New York Red Bulls Image:logo2.jpg

使用Python测试：3.4.2

列表中的两个随机值需要与图像匹配
