Tkinter 从列表中创建按钮，每个按钮都有自己的功能 [英] Tkinter create buttons from list each with its own function

问题描述

我想从列表中创建按钮并根据列表项为每个按钮分配一个功能.我在下面试过，按钮没有响应点击.我看到使用 lambda 函数将参数传递给函数的解决方案，但我想要单独的函数.在 Anaconda 中使用 Python 3.5

I want to create buttons from a list and assign each button a function based on the list item. I tried below and the button doesn't respond to a click. I see solutions where a lambda function is used to pass a parameter to a function but I would like separate functions. Using Python 3.5 in Anaconda

import tkinter as tk

def North():
    print('slected North')

def South():
    print('slected South')

def East():
    print('slected East')

def West():
    print('slected West')

lst = ['North','South','East','West']
win = tk.Tk()
win.title = 'Compass'
for col,Direction in enumerate(lst):
        butName = tk.Button(win, text = Direction, command = Direction)
        butName.grid(row = 1, column = col)


win.mainloop()

推荐答案

您的列表包含字符串；它需要包含功能

Your list contains strings; it needs to contain functions

lst = [North,South,East,West]
