Question

我想结合使用def clicked和def clicked2的功能，因为它们是相同的，但是我不知道该怎么做。我还没有尝试过，但我想不出一种方法。

from tkinter import *
import random
window = Tk()
x = round(random.random()) + 1
m = 7 
window.title("NIM-7 spel") 
window.geometry('350x200') 
lbl = Label(window, text="Player " + str(x) + " next")
lbl2 = Label(window, text="Their are " + str(m) + " coins left")
lbl.grid(column=0, row=1) 
lbl2.grid(column=1, row=0)

def clicked(): 
    global x
    global m
    m -= 1
    if m < 1:
        lol = "Player " + str(x) + " won!"
        res = ""
    else: 
        if x == 1: 
            x = 2
        else: 
            x = 1
        lol = "Their are " + str(m) + " coins left"
        res = "Player " + str(x) + " is next"
    lbl.configure(text=res) 
    lbl2.configure(text=lol)
def clicked2(): 
    global x
    global m
    m -= 2
    if m < 1: 
        lol = "Player " + str(x) + " won!"
        res = ""
    else: 
        if x == 1: 
            x = 2
        else: 
            x = 1
        lol = "Their are " + str(m) + " coins left"
        res = "Player " + str(x) + " is next"
    lbl.configure(text=res)
    lbl2.configure(text=lol)

btn1 = Button(window, text="Take 1 coin", command=clicked)
btn2 = Button(window, text="Take 2 coins", command=clicked2)
btn1.grid(column=1, row=1)
btn2.grid(column=2, row=1)
window.mainloop()

有人知道怎么做吗？

如果使用lambda函数，则可以向tkinter按钮添加参数。已经问了一些相同的问题：

Functions in Tkinter

How to call a function with arguments in "Button" function from "tkinter" python package?

def clicked(value): 
    global x
    global m
    m -= value
    if m < 1:
        lol = "Player " + str(x) + " won!"
        res = ""
    else: 
        if x == 1: 
            x = 2
        else: 
            x = 1
        lol = "Their are " + str(m) + " coins left"
        res = "Player " + str(x) + " is next"
    lbl.configure(text=res) 
    lbl2.configure(text=lol)

btn1 = Button(window, text="Take 1 coin", command = lambda:clicked(1))
btn2 = Button(window, text="Take 2 coins", command = lambda:clicked(2))

传入要减少m的参数作为参数。所以：

def clicked(decrement): 
    global x
    global m
    m -= decrement
    if m < 1: 
        lol = "Player " + str(x) + " won!"
        res = ""
    else: 
        if x == 1: 
            x = 2
        else: 
            x = 1
        lol = "Their are " + str(m) + " coins left"
        res = "Player " + str(x) + " is next"
    lbl.configure(text=res)
    lbl2.configure(text=lol)

然后这样命名：clicked(1)和clicked(2)。

由于将其作为参数传递给Button，因此可以创建虚拟函数：

def clicked1():
    clicked(1)

以及clicked2的类似内容。

有谁知道如何组合这些功能？
