Question

我正在使用tkinter创建一个状态面板，我需要手动更改每个标签的颜色。我想通过向弹出的控制台发出命令来做到这一点。我从对话框中发出命令（例如：redalert(stat1)），将命令与参数分开。我可以为每个标签使用单独的if语句，如下所示：

if 'redalert' in command:
    param = command.split('(')[1]
    param = 'self.' + param.split(')')[0]
        if param == 'self.stat1':
            self.stat1.config(bg='red')
        elif param == 'self.stat2':
            self.stat2.config(bg='red')

但有更紧凑的方式吗？当我试着说param.config(bg='red')时，它认为我正在尝试配置字符串而不是字符串的值。

以下是整个代码：

from Tkinter import *

class App:
    def __init__(self, master):
        self.stat1 = Label(text="Stat 1", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat2 = Label(text="Stat 2", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat3 = Label(text="Stat 3", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat4 = Label(text="Stat 4", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat5 = Label(text="Stat 5", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat6 = Label(text="Stat 6", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat7 = Label(text="Stat 7", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat8 = Label(text="Stat 8", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat9 = Label(text="Stat 9", bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
        self.stat10 = Label(text="Stat 10", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat11 = Label(text="Stat 11", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat12 = Label(text="Stat 12", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat13 = Label(text="Stat 13", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat14 = Label(text="Stat 14", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat15 = Label(text="Stat 15", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat16 = Label(text="Stat 16", bg='#990000', bd=3, relief=SOLID, padx=26, pady=20)
        self.stat1.grid(row=0, column=0)
        self.stat2.grid(row=0, column=1)
        self.stat3.grid(row=0, column=2)
        self.stat4.grid(row=0, column=3)
        self.stat5.grid(row=1, column=0)
        self.stat6.grid(row=1, column=1)
        self.stat7.grid(row=1, column=2)
        self.stat8.grid(row=1, column=3)
        self.stat9.grid(row=2, column=0)
        self.stat10.grid(row=2, column=1)
        self.stat11.grid(row=2, column=2)
        self.stat12.grid(row=2, column=3)
        self.stat13.grid(row=3, column=0)
        self.stat14.grid(row=3, column=1)
        self.stat15.grid(row=3, column=2)
        self.stat16.grid(row=3, column=3)
        root.bind("<F1>", self.callConsole)
    def callConsole(self, master):
        self.commandConsole = Console(root)
        root.wait_window(self.commandConsole.top)
        command = self.commandConsole.commandVar
        if 'redalert' in command:
            param = command.split('(')[1]
            param = 'self.' + param.split(')')[0]
            if param == 'self.stat1':
                self.stat1.config(bg='red')
            elif param == 'self.stat2':
                self.stat2.config(bg='red')
class Console:
    def __init__(self, master):
        self.top = Toplevel()
        self.top.transient(root)
        self.command = Entry(self.top, font=("Helvetica", 15))
        self.command.grid(row=0, column=0)
        self.command.focus_set()
        self.top.bind("<Return>", self.execute)
    def execute(self, master):
        self.commandVar = self.command.get()
        self.top.destroy()
root = Tk()
app = App(root)
root.mainloop()
root.destroy()

我建议将所有统计信息存储在列表中，而不是将每个统计信息存储在自己的变量中。如果您有索引，那么很容易访问特定的统计数据。

class App:
    def __init__(self, master):
        self.stats = []
        idx = 0
        for i in range(4):
            for j in range(4):
                stat = Label(text="Stat {}".format(idx+1), bg='#990000', bd=3, relief=SOLID, padx=30, pady=20)
                stat.grid(row=i, column=j)
                self.stats.append(stat)
                idx += 1
        root.bind("<F1>", self.callConsole)
    def callConsole(self, master):
        self.commandConsole = Console(root)
        root.wait_window(self.commandConsole.top)
        command = self.commandConsole.commandVar
        if 'redalert' in command:
            digits = [c for c in command if c.isdigit()]
            number = int("".join(digits))
            self.stats[number-1].config(bg="red")

（callConsole中使用的数字提取技术仅用于演示目的，可能不适合您的目的，因为它非常容忍奇怪的输入。例如，用户可以键入＆＃34; foo 1 redalert 2 troz＆＃34;它将使12号亮起来）
