Python 单击Tkinter中的按钮后如何更新标签？

我正在尝试使用python Tkinter制作一个仿制的Cookie Clicker，并且在用户购买增量器之后，我正在尝试更新价格标签。

单击按钮后如何更新标签？

所有这些参数都可作为对象的属性使用。您需要更改现有对象，而不是创建新对象

from tkinter import *

win = Tk()
win.minsize(250, 250)
win.title("Point Clicker")
win.resizable(0, 0)

# Make Save fuction
SaveButton = Button(win, text="Save Progress", command=None)
SaveButton.place(x=75, y=215)

value = 1
IncreaserPrice = 50
point = 0
print("You have " + str(point) + " points")

def AddPoint():
    global point
    point = point + value
    print("You have " + str(point) + " points")

def BuyDoubler():

    global value, point, IncreaserPrice

    if point > IncreaserPrice or point == IncreaserPrice:
        print("You have bought the Point Doubler")
        value = value + 1
        point = point - IncreaserPrice
        IncreaserPrice += 50
        Price1 = Label(win, text="Price = " + str(IncreaserPrice) + " points")
        print("You have " + str(point) + " points left")


    else:
        print("You dont have enough points for this")


Clicker = Button(win, text="Click for points", command=AddPoint)
Clicker.pack()

ClickIncreaser = Button(win, text="Buy Point Doubler", command=BuyDoubler)
ClickIncreaser.pack()

Price1 = Label(win, text="Price = " + str(DoublerPrice) + " points")
Price1.pack()

win.mainloop()

你知道你可以在

if

语句中使用

=

而不是两个单独的比较吗？

你可以在

打包

或

网格

使用

label.config

方法打包后更新tkinter标签。下面是一个例子：

   Price1.text = "Price = %d points" % IncreaserPrice

已被

pack

ed更新的标签显示标签已更新，而不是标签。

哦，是的，我不小心使用了两个运算符，而不是一个。@Debil.exe非常希望您能继续您有趣的小项目。谢谢！我将来也会做很多游戏！谢谢你的帮助！

import tkinter as tk

screen = tk.Tk()
label = tk.Label(text="Label")
label.pack()
label.config(text="Label updated")
screen.mainloop()
