推荐答案

使用前景和背景关键字可以在菜单中添加颜色.看看.

Adding colors to the menu is possible with the keywords foreground and background; take a look.

try:
    import tkinter as tk
except:
    import Tkinter as tk

root = tk.Tk()

menubar = tk.Menu(root)

filemenu = tk.Menu(menubar,tearoff=0)

filemenu.add_command(label="text 1")
filemenu.add_command(label='text 2', foreground = 'blue')
filemenu.add_command(label='text 3',background='green')

# entire dropdown menu has been given this color
editmenu = tk.Menu(menubar,tearoff=0,foreground = 'green')
editmenu.add_command(label='copy')
editmenu.add_command(label='paste')

menubar.add_cascade(menu=filemenu, label="File")
menubar.add_cascade(menu=editmenu, label="edit")

root.config(menu=menubar)

root.mainloop()

从预定义的列表中选取颜色，涉及一个for循环.

Taking colors from a predefined list, involves a for-loop.

try:
    import tkinter as tk
except:
    import Tkinter as tk

root = tk.Tk()

menubar = tk.Menu(root,foreground='red')
filemenu = tk.Menu(menubar,tearoff=0)

text = ['text 1', 'text 2', 'text 3']
color = ['green','red','yellow']

for a,b in zip(text,color):
    filemenu.add_command(label=a,foreground=b)

menubar.add_cascade(menu=filemenu, label="File")
root.config(menu=menubar)
root.mainloop()

希望将代码转换为2.7.
